Value Collection A996013 Square Head Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION A996013 is a 1/2-13 UNC square head bolt manufactured from Grade 5 steel with an uncoated finish. The square head design provides four flat bearing surfaces, making it well-suited for applications where a wrench or tool must grip the head securely, or where the head needs to seat against a square hole to prevent rotation. At 1-3/4 inches in length under head and a 1/2-13 UNC thread specification, this bolt meets ANSI/ASME B18.2.1 dimensional standards. It is a standard fastener used across mechanical, structural, and industrial assembly work by millwrights, pipefitters, machinists, and general tradespeople.

This square head bolt is appropriate for general-purpose fastening in residential, commercial, and light industrial settings. Common applications include machinery assembly, pipe hanger hardware, structural steel connections, and equipment mounting where square head fasteners are specified or preferred. The uncoated finish suits indoor or dry environments. Grade 5 steel provides a reliable mid-range tensile strength suitable for moderate-load fastening applications. Sold in a package quantity of 25 per order.
