Round head bolt with a square neck under the head, and a unified thread pitch, made from austenitic alloy stainless steel.

The same design advantages as a low carbon carriage bolt but for use in environments requiring general atmospheric corrosion resistance.

Used to attach plywood, soft wood or metal to metal. Serrated washer design adds greater holding power to components subject to vibrations caused by repeated movements The 1/4-inch diameter screws, for instance, are commonly used to attach reinforcing strut or L-angle to garage doors.

AISI 1016 - 1024 or equivalent steel

HIGH QUALITY ZINC PLATED STEEL: Made of 100% high quality durable steel with hard zinc plating, built to last years with no wear and tear

RUST RESISTANT: Zinc Plating provides an excellent corrosion resistant shell for a long lasting cost effective fastener

Hex Washer Head Sheet Metal Screws are known to be convenient and versatile. Great to have while working with sheet metal environment. Suitable for indoor and outdoor applications

For use in Steel, Sheet Metal, and attaches Metal or Steel to Metal or Sheet Metal Steel. Installed with 5/16" Hex Driver

Coarse thread Drywall--Sharp point: For attaching drywall to wood studs or to 25 gage metal studs. Particle Board Screw: Designed specifically for use in dense woods, especially man-made types such as chipboard and particle board

AISI 1018 or equivalent steel

Ideal for attaching hinges into soft woods. The deeper thread design offers greater resistance to pull-out forces

C1022 case-hardened steel

Building Code Approved. The diamond tip allows for superior penetriating into hard materials. Great for anchoring items to concrete, brick, block, or other masonry materials. Blue ceramic coating exceeds 500/hrs salt spray resistance

An externally threaded, hardened screw with a double lead, consisting of alternating raised and lowered threads with notches cut into the raised threads, and a diamond-shaped, nail-type point. Cuts its own threads and when used in concrete, block or brick. Eliminates the need for an anchor when used in light or medium-duty applications. When used in concrete, it can be removed and re-driven into the same hole. Special carbide bits are recommended for driving concrete screws into masonry.

Low-profile head can remain in place when panels are down

Hurricane bolts can also be referred to as sidewalk bolts

A fastener with an extra wide head, twinfast thread and self drilling point. The head is an integrally formed round washer with a low rounded top that is approximately 75% the diameter of the washer.

Common usage is to attach wire or metal lathe to metal studs of a thickness between 12 - 20 gauge.
