Value Collection SQNI20370-100BX 3/8-16 Steel Square Nut

Product Description

The VALUE COLLECTION SQNI20370-100BX is a 3/8-16 steel square nut with a zinc-plated finish, sold in a box quantity of 100. Square nuts provide a larger bearing surface than standard hex nuts, reducing the likelihood of pull-through in wood, channel stock, and structural framing. The right-hand 3/8-16 thread is one of the most common coarse-thread fastener sizes in the inch system. Each nut measures 5/8 inches across the square width and 21/64 inches in overall height. The zinc plating provides a baseline level of corrosion resistance for general-purpose indoor and sheltered outdoor use. Electricians, HVAC installers, plumbers, and general contractors regularly stock this size for strut channel, panel work, and mechanical assemblies.

These square nuts are suited for residential and light commercial construction and mechanical work. Common applications include securing components to unistrut or Kindorf channel, bolting through wood framing members, and general assembly where a wrench-free or back-held nut is needed. The coarse 3/8-16 thread engages quickly and resists cross-threading in field conditions. The 100-count box format makes this practical for stocking a service van, job-site bin, or shop inventory.

Key Features

• 3/8-16 coarse right-hand thread for broad fastener compatibility
• Steel construction with zinc plating for corrosion resistance in general-use environments
• 5/8 inch square width provides increased bearing surface compared to hex nuts
• 21/64 inch overall height — compact profile for tight assemblies
• 100-count box quantity reduces per-unit cost for high-volume applications
• Inch-system dimensions for use with standard SAE tooling and fasteners

Compatibility

Designed for use with any 3/8-16 inch threaded bolt or rod in standard inch-system fastener assemblies, including strut channel, structural framing, and general mechanical applications.

Installation Notes

Square nuts are typically installed by hand-starting the nut onto the bolt before tightening with an appropriate wrench or socket. In channel or strut applications, the nut is dropped into the channel and rotated 90 degrees to lock in place before the bolt is driven. Always verify thread engagement is adequate before applying final torque. Follow applicable codes and structural requirements for the specific assembly type.
