SS Hex Cap Screws

Type 18-8 Stainless Steel Hex Head Cap Screws

Hex head cap screws are similar to hex bolts and differ mostly in that they are manufactured to tighter tolerances. Hex head cap screws also have a slight circular protrusion, like a thin washer, under the head.


Typically, they are used for fastening metal hardware to wood or other metal members, and for joining wood members.


Our stock may be of American or foreign (Taiwan, Japan, Korea, or Switzerland) manufacturer, or a mixture of both.
