Value Collection 3756BMQ Square Head Bolt 3/8-16 Unc

Product Description

The VALUE COLLECTION 3756BMQ is a square head bolt designed for general fastening applications where a wrench-friendly head profile is required. It features a 3/8-16 UNC thread and measures 3.5 inches in length under the head. Manufactured from Grade 2 steel with an uncoated finish, this bolt meets ANSI/ASME B18.2.1 dimensional standards. Square head bolts are commonly used in wood construction, agricultural equipment, and structural assemblies where the head must be gripped or countered with a wrench or socket. The uncoated finish is suited for dry or protected indoor environments.

This bolt is appropriate for residential and light commercial construction, machinery assembly, and agricultural or industrial maintenance applications. The 3/8-16 UNC thread is a standard coarse-thread pattern widely used across North American fastener applications. Trades and contractors reaching for a reliable general-purpose square head bolt for timber framing, equipment mounting, or structural connections will find this a straightforward fit.

Key Features

• Square head profile allows secure wrench or socket engagement to resist rounding
• 3/8-16 UNC coarse thread for broad compatibility with standard nuts and tapped holes
• 3.5 inches of thread length under head accommodates a range of material thicknesses
• Grade 2 steel construction meets ANSI/ASME B18.2.1 dimensional standards
• Uncoated finish suitable for protected or dry service environments

Compatibility

Designed as a standard ANSI/ASME B18.2.1 square head bolt compatible with 3/8-16 UNC nuts, washers, and threaded inserts used in general construction and mechanical fastening applications.

Installation Notes

Installation is typically performed by carpenters, millwrights, or general tradespeople using a wrench or socket set sized for the square head. Always ensure the mating nut or threaded hole matches the 3/8-16 UNC thread standard before driving. Do not overtighten Grade 2 fasteners in brittle or low-bearing-strength materials. Verify that the uncoated finish is acceptable for the service environment before installation, as bare steel is susceptible to corrosion in wet or outdoor exposures.
