Shorter than other internally threaded anchors, these anchors are capable of attaching to shallow materials with ease. Also known as caulk-in and machine-bolt anchors, they consist of a lead sleeve around an internally threaded zinc cone. When installed, the cone expands the sleeve to hold it firmly inside the hole.

USS and SAE (Type A) are the most widely used types of washers. SAE standard washers generally have a smaller ID and OD than USS standard washers. Commonly used with bolts, screws, and nuts, zinc coated options provide mild corrosion resistance while the stainless steel versions provide excellent corrosion resistance and may be mildly magnetic.

Compared to regular flat washers, these split lock (or spring lock) washers reduce the likelihood that your fastened joint will loosen under shock or vibration. Under compression, spring tension forces the split ends to dig into mating surfaces and hold tight. Available through your local City Electric Supply. Click here to find a branch near you.

Also known as a metal lath screw, a self-drilling screw is designed with a drill-shaped point to easily cut through sheet metal or steel, eliminating the need to create a pilot hole. This fully threaded screw has a one-piece hex washer head with a wide, flat bearing surface that reduces the possibility of crushing surfaces. Available through your local City Electric Supply.

A self-tapping screw is designed to create its own hole in wood, plastic or metal materials as it is being driven (it does not necessarily require a pilot hole). Tapping screws are beneficial in applications that involve consistent maintenance and are especially helpful when two different materials are being attached together. This tapping screw has a pan head and a flat bearing surface. The combination drive accepts both Phillips and slotted drivers. Learn More

A self-tapping screw is designed to create its own hole in wood, plastic or metal materials as it is being driven (it does not necessarily require a pilot hole). Tapping screws are beneficial in applications that involve consistent maintenance and are especially helpful when two different materials are being attached together. The square drive on this tapping screw reduces driver slippage and allows for more driving power than a Phillips head. Available through your local City Electric Supply.
