The VALUE COLLECTION 5016BMQ is a square head bolt designed for general fastening applications in structural, mechanical, and industrial assemblies. It features a 1/2-13 UNC thread size with 1 inch of length under the head, manufactured from Grade 2 steel in an uncoated finish. The square head profile allows wrench engagement on all four sides, making it well-suited for installations where clearance or grip orientation is a factor. This bolt conforms to ANSI/ASME B18.2.1 dimensional standards. Professionals in mechanical, construction, and industrial trades rely on this fastener type for dependable, code-compliant connections in both new construction and retrofit work.
This square head bolt is used in a wide range of residential and commercial mechanical assemblies, wood framing connections, machinery mounting, and general structural fastening. The 1/2-13 UNC coarse thread pattern provides strong engagement in steel and other metal substrates. The uncoated finish is appropriate for interior applications or where secondary coatings or treatments will be applied on site. Sold individually per package with a minimum order quantity of 50 pieces.
Designed as a general-purpose square head bolt for use in mechanical, structural, and industrial assemblies requiring 1/2-13 UNC thread fasteners conforming to ANSI/ASME B18.2.1.
Installation is typically performed by millwrights, ironworkers, pipefitters, or general mechanical contractors using standard open-end or box wrenches sized for a 1/2-13 bolt head. Always de-energize and lock out equipment before fastening components in mechanical or electrical enclosure assemblies. Apply fasteners to the manufacturer-specified torque range for Grade 2 hardware per applicable ASME or job specification requirements. Do not use impact tooling without a torque-limiting socket to avoid overloading the Grade 2 material rating.
