Value Collection KP56354 Hex Head Cap Screw 3/8-16 X 7 in

Product Description

The VALUE COLLECTION KP56354 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications. Measuring 3/8-16 thread size at 7 inches in length under head, this fastener uses Unified National Coarse (UNC) thread form and features partial threading along the shank. The uncoated finish is standard for applications where a secondary coating or plating will be applied, or where coating is not required by the assembly spec. Manufactured to ASME B18.2.1 dimensional standards, this screw is appropriate for structural, mechanical, and industrial assemblies that require a Grade 8 tensile rating. Installed using a standard hex wrench or impact driver with the correct socket size.

This cap screw is suited for heavy-duty fastening in residential, commercial, and industrial applications where high clamping force and shear resistance are required. Partially threaded shanks provide a smooth bearing surface for applications with close-tolerance holes or where shank alignment is critical. Common install scenarios include mechanical equipment mounting, steel fabrication, HVAC equipment structural fastening, and general trade assembly work. The 3/8-16 UNC thread pattern is one of the most widely used coarse-thread sizes across trade industries.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-16 UNC thread — widely compatible with standard nuts and tapped holes
• 7 inches length under head with partial threading for smooth-shank bearing surface
• Uncoated finish — suitable for plating, coating, or use as-is per assembly requirements
• Manufactured to ASME B18.2.1 dimensional standard for consistent head geometry and thread form
• Sold in packages of 25 with a minimum order quantity of 1

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, flat washers, lock washers, and tapped holes conforming to UNC thread standards in inch-system fastener applications.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque specifications for Grade 8 hardware. Always confirm proper thread engagement and ensure the mating nut or tapped hole is rated for Grade 8 loading before assembly. Do not mix inch and metric hardware. Follow applicable mechanical or structural codes for the specific application, and inspect fasteners for thread damage before installation.
