SPIROL

SPIROL's KP200 Straight Knurled Pins have straight knurls that span the full length of the pin. Straight Knurled Pins are commonly used in applications where the pin is subjected to rotational forces to transmit torque as well as to resist rotational movement of a mating component. KP200 Straight Knurled Pins are available in metric diameters ranging from 2.5mm to 6mm and in inch diameters ranging from .094" (3/32) to .250" (1/4) in low carbon steel and austenitic stainless steel.

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.

SPIROL's FH200 Headed Straight Knurled Pin has the same body style as the KP200 Straight Knurled Pin, with the addition of a head. A Headed Pin is typically used to provide a positive stop or to retain a thin component to a thicker component within an assembly. FH200 Headed Straight Knurled Pins have a flat head, however they are available to order with a round head (RH200) to meet specific application requirements. Similar to the SPIROL Series KP200 Straight Knurled Pin offering, SPIROL's Series FH200 Headed Straight Knurled Pins are available in metric diameters ranging from Ø2.5mm to Ø6mm and inch diameters ranging from Ø.094" (3/32) to Ø.250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL's Barbed Pins were created specifically for use in flexible plastics where optimum resistance to axial force is desired. The raised barbs are angled backwards, opposite the direction of insertion. After installation, the plastic will backfill into the area around the barbs resulting in maximum retention. Barbed Pins are ideal for applications requiring high pull-out (tensile) strength, and to prevent disassembly (i.e. tamperproof ). Barbs are not appropriate for brittle plastics or those containing high percentages of fillers. As barbs are a radial feature, they do not resist rotation of two components relative to one another. For this requirement, a straight or helical knurl should be used. All Barbed Pins are provided with a generous pilot to facilitate alignment with the hole and ease installation.

SPIROL's BP100 Press-N-Lok™ Pin has opposing barbs on each end of the pin and is designed to permanently retain two plastic components to each other such as two halves of a plastic enclosure. Press-N-Lok™ Pins are installed in two stages: First, press the pins into one half of the plastic housing. Next, align the other half of the housing with the exposed pins and press into place. During installation, the plastic will backfill into the area around the barbs resulting in maximum resistance to axial force. SPIROL's Press-N-Lok™ Pins are manufactured from lightweight, lead free aluminium as a standard, and available to order in austenitic stainless steel. BP100 Press-N-Lok™ Pins are available in diameters ranging from 2mm to 4mm.

SPIROL's FH400 Headed Barbed Pin has a series of barbs extending down the entire length of the pin. Headed Barbed Pins are a great replacement for self-tapping screws in plastic assemblies as Barbed Pins are installed into standard moulded (or drilled) holes, they install much faster than screws, and they eliminate issues associated with cross-threaded or skewing during installation. Unlike screws that resist back-out (or loosening) by being tightened to a preset torque, Barbed Pins are retained by the plastic backfilling over the aggressively-designed barbs. The head provides a positive stop and is also used to retain a thin component to a thicker component within an assembly. SPIROL's FH400 Headed Barbed Pins are available in metric diameters ranging from Ø2mm to Ø6mm and inch diameters ranging from Ø.078" (5/64) to Ø.250" (1/4) in low carbon steel and austenitic stainless steel.

SPIROL designs and manufactures specific types of Solid Pins to meet the performance and assembly requirements of common niche applications. These Solid Pins are variations of our standard product either manufactured from specific material, have a specific finish or undergo specific processing to meet performance, corrosion, compatibility and assembly requirements for the specific application. These pre-designed application-specific series of Solid Pins help companies shorten the design cycle to confidently launch their product quickly to the market with a pinning solution that has been tested and proven within their assembly.

SPIROL's Series LP500 Latch Pins for Plastics are designed with a barb located under the head with a barb length equal to the width of the outermost section of the assembly. The remaining length of the LP500 Latch Pin is smooth without any other retention features. This allows the LP500 Latch Pin for Plastic to easily align and freely install through all of the holes with a plastic assembly until the barb makes contact with the final hole to securely lock the pin in place. Once fully installed, the handle will pivot freely around the non-barbed end of the stationary pin. The head prevents the LP500 Latch Pin from being over-installed, and enables the pin to be mechanically oriented for automatic installation. Manufactured from lightweight, lead free aluminium, SPIROL's LP500 Latch Pins for Plastics are available in three standard diameters: 3mm, 4mm and 5mm.

Series RH600 Twist-Lok™ Pins replace costly screw machined pins and eliminate problematic installation of screws and rivets. The helical knurl minimises stress during installation by rotating as it engages the hinge. Corrosion-resistant material and a rounded burr-free head improve installed appearance. Axial and radial forces induced in the hinge eliminate the tendency for the pin to creep and maintain hinge tension.
