Threaded Lock Washers

Threaded Protection Plugs for NPT Threads protect threads and fittings from damage during production, storage, and shipment, ensuring that they remain in good condition and ready for use when needed. The protection plug protects from contaminants like dirt, dust, debris, and moisture from the hole.

It may be installed by hand or with a 12-point socket head, screwdriver or wrench. This threaded plug is suggested for usage where strength and abrasion resistance are required since it can tolerate temperatures ranging from -40F to 230F | -40C to 110C. Suitable for Metric threads. Used in various applications, including hydraulic, pneumatic and general engineering industries.

Series Code :SR1002, SR5762, SR1077, SRF0029

These Wide Flange Threaded Protection Plugs protect threads and fittings from damage during production, storage, and shipment, ensuring they remain in good condition and ready for use. Their nitrile gasket seals the plug to the mating surface for leak-tightness. The protection plug protects from contaminants like dirt, dust, debris, and moisture from the hole.

Its wide flange design keeps any paint flakes from the hole when removed. It is easy to install or remove by hand, screwdriver, or torque wrench. Due to its Nylon material, it is recommended for intermittent temperatures from -40C to +100C. Used in various applications, including hydraulic, pneumatic and general engineering industries.

Our Locking Washers are made from metal, with either a stainless steel or zinc plated finish. These External Tooth Lock Washers have been developed for locking screws, bolts and nuts in place, and offer ideal prevention for the loosening of PCB spacers caused by vibrations.The Tooth Lock Washer, also known as an Electrical Contact Washer, has tooth-like serrations on the external diameter that help the toothed washer prevent bolted joints from loosening, through the use of friction.Our stainless steel toothed washers offer good corrosion and wear resistance. The zinc plated external tooth washer option, is ideal for applications where a high mechanical strength is needed. The lower material cost makes it an alternative to brass, when conductivity is not a critical issue. Zinc plating provides a professional finish and is RoHS compliant.

• DIN rated
• Compatible Screw Sizes: M2 and M3.

Waist Shaped Knobs have a curvy, hourglass shape that provides a firm gripping surface that is also comfortable. These durable knobs fit on to threaded applications and are resistant to oils, fuels, and greases.

Female Tapered Wing Knobs are designed to give good leverage with each turn making them ideal for applications that require frequent tightening and loosening. These tapered plastic knobs with steel inserts are easily gripped and durable.
