Value Collection 50192BMQ Square Head Bolt 1/2-13 Unc

Product Description

The VALUE COLLECTION 50192BMQ is a square head bolt designed for heavy-duty fastening applications in construction, industrial machinery, and structural assembly. It features a 1/2-13 UNC thread size and a 12-inch length under head, providing substantial grip depth for through-bolting thick stock or structural members. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI/ASME B18.2.1 dimensional standards. The square head profile allows high torque application using a wrench or socket without rounding, making it well suited for high-load connections where a standard hex head may not provide adequate drive surface.

This bolt is used in general industrial, agricultural, and structural applications where a square head drive is specified or preferred. Typical installations include timber framing, equipment mounting, conveyor systems, and utility infrastructure work. The 12-inch shank length accommodates thick material stacks or applications requiring deep thread engagement with a nut. Tradespeople, millwrights, ironworkers, and maintenance mechanics working with heavy steel or wood assemblies will encounter this fastener regularly.

Key Features

• 1/2-13 UNC thread for broad nut and hardware compatibility
• 12-inch length under head suits thick-stock and through-bolt installations
• Square head profile provides strong wrench purchase and resists rounding under high torque
• Grade 2 steel construction meets ANSI/ASME B18.2.1 dimensional standards
• Uncoated finish suitable for indoor or protected applications

Compatibility

Designed as an OEM-style replacement or direct-use fastener compatible with any 1/2-13 UNC threaded nut or tapped hole meeting ANSI/ASME B18.2.1 standards.

Installation Notes

Installation is performed by millwrights, ironworkers, or maintenance mechanics using standard open-end, box, or socket wrenches sized for a square head profile. Always ensure the mating nut or tapped hole is rated for the same thread standard and material grade before assembly. Follow applicable structural or mechanical codes for fastener torque class and joint design. Inspect threads for damage before installation and do not force-thread into misaligned holes.
