It features a 5\/8-11 UNC thread standard and a 3-1\/4 inch length under head. Constructed from Grade 2 steel with an uncoated finish, this bolt is suited for use in non-corrosive environments where standard carbon steel fastener strength meets application requirements. Square head bolts are commonly installed by maintenance technicians, pipefitters, millwrights, and general contractors working on equipment mounting, pipe support, or structural connections.\u003c\/p\u003e\u003cp\u003eThis fastener is appropriate for residential and light commercial applications where UNC coarse thread engagement is required.
