Square Head Set Screws crafted from case-hardened steel deliver exceptional strength and wear resistance for demanding machinery. The cup point design provides a positive bite that resists loosening in dynamic applications. Sized as 5/16-18 x 1/2 and ideal for securing components where a square-head drive is preferred.
