This 5/16″ x 3-1/2″ mounting screw from StairSupplies is made from case hardened carbon steel. Case hardening gives the screw a tough, wear-resistant outer surface, so it holds up when driven into dense material and resists stripping. It is a dependable choice for mounting railing posts and brackets where a strong, structural connection matters. It is a smart pick for contractors and DIYers who want hardware that holds up through installation.
