Prime-Line 400 Series 5/16 in. Stainless Steel Internal Tooth Lock Washers (25-Pack)

Prime-Line 400 Series 5/16 in. Stainless Steel Internal Tooth Lock Washers (25-Pack)

Internal tooth lock washers feature teeth that help to prevent loosening of a nut or bolt by digging into the surface. For maximum holding power, use 1 between the surface and the bolt head and use another 1 between the surface and the nut. It is best to use these with smaller bolt heads and in applications where there is a desire to not have exposed teeth. Lock washers are great for use in cases where the bolt may be subject to vibration.


Everbilt 1/4 in. Stainless Steel Lock Washer (50-Pack)-800042

Everbilt 1/4 in. Stainless Steel Lock Washer (50-Pack)-800042

Lock washers are essential fasteners to keep on hand. They are used with a bolt or screw to evenly spread the load over a wider area. Lock washers place tension against a nut to prevent loosening due to vibration. Available in a variety of sizes and finishes.


Prime-Line M14 Metric Zinc Plated Steel Medium Split Lock Washers (10-Pack)

Prime-Line M14 Metric Zinc Plated Steel Medium Split Lock Washers (10-Pack)

Split lock washers can help to prevent nuts or bolts from loosening by adding a spring tension force along with split edges that are designed to dig into the nut and material being fastened. For additional loosening resistance, use a lock washer on the nut side as well as on the head side. Split lock washers may not be as effective on extremely hard metals as the edges at the split cannot dig in to the surface as well.


Desert Wanderer Lock Washer Hex Nut Coil Scavenged Industrial Metal Hardware Suede Leather Necklace

Desert Wanderer Lock Washer Hex Nut Coil Scavenged Industrial Metal Hardware Suede Leather Necklace

Another slight variation on a previous desert wanderer piece! Layered lock washers below a hex nut and coil. Arrangement measures 1-1/4 inches wide and drops from suede knot at 2 inches in length. On double tan 100% raw suede leather cord. Secured with wire, lanyard and ring. 15 inches in length, closer to a choker size. If you’d like this to be longer I can always add a few extra rings. Scavenged hardware has a nice rust patina that has been properly washed and treated so you can wear it safely and comfortably. Has a nice weight.
