The effective protection against self loosening and unscrewing. The "NSK" LOCK WASHER is the improved design of the "SK" LOCK WASHER. It also prevents self-loosening of screwed joints and damage to the bearing surfaces and consequent variations in the tightening torques, as they occur in threadlockers with teeth are avoided with lock washers through the special geometrical shape of the locking edges even better than the proven "SK" LOCK WASHER.

The contact lock washer to NFE 25-511 and SN 70093 with grooved surface provides the designer the ability to secure wobble-prone screw effectively. It is particularly suitable for use on slot fasteners, dynamic cross-loaded to the screw connections and applications that require high biasing forces. Operational: The contact wheel ensures positively spring and a form-fitting locking. Form S = narrow - for small headrests Form M = average - for normal headrests Form B = wide - for large pressure transmission surfaces and slot fasteners Form K = serrated - for electrically conductive connections with contact teeth (SN 70093)

According to Bahn-Norm BN 208012-T6 and SN60727 The reliable security device to prevent wide range of bolted assemblies from unscrewing and loosening. The locking edge washers provides a effective method of securing bolted assemblies that are effected by vibration.

The effective protection against self loosening and unscrewing. The "SK" Serrated Locking Washer prevents self-loosening of screwed joints. Damage to the bearing surfaces and consequent variations in the tightening torques, as they occur in threadlockers with teeth are avoided with lock washers through the special geometrical shape of the locking edges. shape S (small) shape M (middle) shape B (wide) shape Z (for screws with cylindrical head shape) shape K (for electrical contacts)

Washer components Screws with one or two captive rolled on bottom parts Manufactured according to DIN, ISO or customer drawing

Washer-shaped locking head This valuable locking head shape distributes the contact pressure evenly over the component, making it the perfect fastener for riveting soft and brittle components such as plastics and composites. Large clamping range One PolyBulb® blind rivet replaces up to three conventional blind rivets and reduces part variety. Combining multiple dimensions saves handling and storage costs and also permanently reduces the risk of confusion in the workplace. Controlled hole reveal By filling the hole according to the requirements, the PolyBulb® blind rivet creates an optimal connection. Customer benefits: • Washer-shaped blind head formation with large blind head diameter. • Aesthetic setting pattern, only one pronounced closing head • High tensile strength and unbonding force • Locked residual rivet mandrel • Rattle-free application • Process controllable

Metal connectors with self tapping screws are provided for the fast connection of rubber belts using a cordless screwdriver. FTK connectors are also available for round balers and in a special version for grape harvesting machines. Our steel connectors come in galvanised steel or non magnetic stainless steel. FTK connectors can be installed just using a cordless screwdriver because the screws are self tapping. No hole drilling is needed. FTK connectors are available with screws and connecting cables in lengths up to 3,000 mm, depending on belt width. A variety of connecting rods, lock washers and screws is also available for the initial installation of FTK connectors or as spare parts, plus various cordless screwdrivers, a pneumatic screwdriver, brace, PZ 2 cross head bits and a magnetic bit holder.
