Heat / Ultrasonic Inserts are designed for post-mould installation in thermoplastics. Heat and ultrasonic installation yield outstanding performance results. SPIROL offers several different series of Heat/Ultrasonic Inserts available in a long and short version of each thread size. Long lengths maximize torque and pull-out resistance, while short lengths are good for less stringent requirements at lower cost and shorter installation times. Some styles are available with or without a head. The head provides bearing surface for the mating component that also prevents jack-out (or when used in reverse, can prevent pull through). However, adding a head results in additional cost raw material of a larger diameter is required to create the head. Some non-headed Inserts are symmetrical – thus eliminating the need to orient the Insert prior to installation.

The course external thread of SPIROL's Self-Tapping Insert forms an internal thread within a molded or pre-drilled hole during the installation process into a plastic assembly. SPIROL Series 10 Self-Tapping Inserts are thread forming Inserts best suited for softer thermoplastics or thermosets. Self-Tapping Inserts provide the best pull-out resistance for a post-mold installed Insert, yet generally cost more than their post-mold counterparts. The external threads are designed with a thin profile to minimize induced stress in the plastic and have a relative coarse pitch to provide the maximum plastic shear surface to resist pull-out.

SPIROL's DP100 Straight Pins have smooth outer diameters with no retention features such as knurls or barbs. When used as a press-fit pin, the DP100 Straight Pin is pressed into a hole sized slightly smaller than the diameter of the pin. SPIROL's DP100 Straight Pins are suitable for press fit in host materials that can withstand compression in the order of 0.05mm – 0.08mm (.002” – .003”). The actual recommended hole size for a press-fit depends on the actual host material. It is for this reason that SPIROL Engineering should be consulted for the recommended hole size when DP100 Straight Pins are intended to be press-fit into an assembly. Straight Pins are a great option for applications that do not require the tight tolerances of Machined Solid Pins or Ground Solid Dowels. SPIROL Series DP100 Straight Pin consists of metric diameters ranging from Ø2mm to Ø6mm and inch diameters ranging from Ø.078" (5/64) to Ø.250" (1/4).

Offered with or without a head, Straight Pins are distinguished by their uniformity. The chamfered ends are more consistent than tumbled edges—making installation with automatic assembly equipment more reliable. Straight Pins are retained by compressing the host, not the inflexible solid pin. They are suitable for use in plastics for press-fit applications limited to those cases where the host material can withstand compression in the order of 0.05mm – 0.08mm (.002” – .003”). Straight Pins are often used to replace Ground Dowels in applications that do not require the tight tolerances of a Ground Dowel.

SPIROL Standard Slotted Spring Pins SPIROL Standard Slotted Spring Pins have a slot width narrower than the wall thickness and thus do not nest or interlock. This feature, combined with a smaller expanded (pre-insertion) diameter, results in a number of advantages for SPIROL Standard Slotted Pins compared to ISO 8752 pins including: • Lower insertion force and smoother insertion. • Rounder pins, which in turn results in better conformance of the pin to the hole wall and eliminates the edge of the slot damaging the hole during insertion. • Lower stress in the spine of the installed pin. This results in longer pin life in shock or fatigue applications. • Ability to use automatic vibratory feeding of pins for installation without interlocking. • Plating of pins for additional corrosion resistance or appearance without “touch marks” or the bonding of nested pins.

SPIROL manufactures Coiled Spring Pins out of 316 stainless steel to meet specific application requirements. Type 316 stainless steel is similar to 302/304 stainless steel with a slightly higher nickel content and the addition of molybdenum. The molybdenum content increases the chemical resistance of this alloy greatly. 316 exhibits superior pitting resistance against sea water, acetic acid vapors, chlorides, sodium and calcium brines, hypochlorite solutions, phosphoric acid, and the sulfite liquors and sulfurous acids used in the paper and pulp industry. This alloy is also austenitic, non-magnetic and non-hardenable using conventional methods. 316 stainless steel has better mechanical properties at elevated temperatures than 302/304 and offers excellent mechanical integrity at subzero temperatures. Typical applications for SPIROL's 316 Stainless Steel Coiled Pins include the following: marine, processing equipment, industrial, oil and gas and medical.

The Series 500 Extra Light Duty Coiled Pins were specifically designed for use in soft or fragile materials. The 1½ coil formation ensures that the radial force exerted against the hole wall does not exceed the strength of the hole material to prevent deformation. These pins are also an economical solution where pin strength is not a major design consideration. Typical applications for Series 500 Extra Light Duty Pins include: hinge pins in plastic or ceramic assemblies, alignment pins, and fastening applications where the hole is close to an edge of an assembly component.

SPIROL's Series 880 Coiled Spring Pin was designed specifically for use as the hinge pin for PC board card lock and ejector clip mechanisms. The quality of the hinge is unsurpassed by other fastening methods due to the low insertion force and compression of the pin during and after installation. As with all Coiled Spring Pins, the Series 880 hinge pin for PC board card locks and ejector clips is self-retaining, and thus no secondary processes are required for retention. The Coiled Pin's uniform radial spring force results in a controlled hinge movement that remains consistent throughout the life of the assembly.

The Series 550 Cosmetic Coiled Pin was designed specifically for cosmetic cases to ensure the perfect balance of strength and flexibility. The 1-1/2 coil construction ensures that the Cosmetic Coiled Pin exerts sufficient radial force to achieve the long-term desired swing torque while protecting the plastic from excessive stresses. The use of SPIROL Series 550 Cosmetic Coiled Pin will simplify your design and manufacturing process. Uniform radial spring force results in controlled hinge movement and a hinge quality that remains consistent over time. Controlled hinge movement is achieved with wider tolerances and lower moulding costs than when a Solid Pin or cut wire is used. Finally, low insertion force and compression of the pin during installation minimises hinge stress and scrap. The net result is the prolonged useful life of the assembly.

SPIROL invented the Coiled Spring Pin in 1948. Truly an engineered fasteners, the Coiled Pin is available in three duties, light, standard and heavy, to enable the designer to choose from the optimum combination of strength, flexibility and diameter to suit different host materials and application requirements. Their shock absorbing design dampens forces and vibration to prevent hole damage and prolong assembly life. Light Duty Coiled Spring Pins are generally recommended for soft, brittle or thin materials such as plastics, aluminium, die castings, ceramics, and where holes are located close to an edge of the assembly. In situations not subjected to significant loads, such as when used purely for alignment or as an axle, light duty Coiled Pins are often used because of easy installation resulting from lower insertion force.

While Coiled Spring Pins are extremely versatile self-retaining fasteners that can be used for many different functions, SPIROL has designed several series of Coiled Pins to meet the nuances and performance requirements of some particular niche applications. These Coiled Spring Pins are variations of our standard product either manufactured from special material, have a special finish or undergo specific processing to meet performance, corrosion, compatibility and assembly requirements for the specific application. These pre-designed application-specific series of Coiled Pins help companies shorten the design cycle to confidently launch their product quickly to their market with a pinning solution that has been tested and proven within their assembly.

SPIROL's Knurled Pins are manufactured with two different knurl types: straight knurls and helical knurls. Unlike a Straight Pin, where retention is provided by the uniform interference between the pin and hole, Knurled Pins are designed to cut into the host. The displacement of the host material into the valleys of the knurls yields more frictional contact area between the Knurled Pin and hole; thus resulting in higher retention. Solid Pins with retention features such as knurls and barbs allow for wider hole tolerances than Solid Pins without retention features (i.e. Straight Pins).

SPIROL's KP300 Helical Knurled Pins have helical knurls that span the full length of the pin. The 30° helical knurls cause the pin to rotate during installation into the hole. Helical Knurled Pins offer higher insertion and retention than Straight Knurled Pins. However, KP300 Helical Knurled Pins are not typically recommended when the pin will be subjected to rotational forces as the helical knurl will cause the pin to either "unscrew" itself from the hole or further imbed itself into the hole. KP300 Helical Knurled Pins are available in metric diameters ranging from 2mm to 6mm and in inch diameters ranging from .078" (5/64) to .250" (1/4) in low carbon steel and austenitic stainless steel.
