Value Collection 837277PS Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 837277PS is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, structural fixtures, and industrial equipment. It features a 3/8-16 UNC thread size and measures 4 inches in length under the head. The 5/16-inch hex drive socket accepts a standard hex key or Allen wrench for installation. Constructed from alloy steel with a zinc-plated finish, this fastener delivers solid corrosion resistance alongside the tensile strength required in demanding trade and industrial settings. It is sold individually with a minimum order quantity of 10 units.

This cap screw is suited for residential and commercial mechanical work, fabrication shops, HVAC equipment assembly, and general industrial maintenance. The 3/8-16 UNC coarse thread pattern provides reliable thread engagement in standard tapped holes and is compatible with common UNC nuts and threaded inserts. The partially threaded shank allows the unthreaded portion to bear shear loads, making it appropriate for joint connections where load distribution across the shank is advantageous.

Key Features

• 3/8-16 UNC coarse thread for compatibility with standard tapped holes and UNC fastener hardware
• 4-inch length under head accommodates thicker material stacks and deeper engagement
• Partially threaded shank supports shear load distribution along the bolt body
• 5/16-inch hex drive accepts standard hex keys and socket drivers
• Alloy steel construction provides high tensile and yield strength
• Zinc-plated finish meets ASTM B695 for corrosion resistance in typical indoor and light outdoor environments

Compatibility

Designed as a standard replacement or maintenance fastener for any application requiring a 3/8-16 UNC partially threaded hex socket cap screw with a 4-inch length under head.

Installation Notes

Installation is performed using a 5/16-inch hex key or compatible socket driver. Ensure the receiving threaded hole or nut is clean and free of debris before driving the fastener. De-energize or power down any equipment before accessing fastener locations in electrical or mechanical enclosures. Follow applicable mechanical codes and equipment manufacturer torque guidelines when tightening fasteners in structural or load-bearing applications.
