Product Description

The VALUE COLLECTION 402065PR is a partially threaded hex head cap screw designed for general-purpose mechanical fastening applications. It features a 5/16-18 UNC thread size with a length under head of 2-1/4 inches. Manufactured from Grade 2 steel with a bright, uncoated finish, this fastener suits a wide range of structural and equipment assembly tasks. Partial threading provides a smooth shank section that resists shear loads and allows for precise clamping. Trade professionals in HVAC, plumbing, electrical, and general mechanical service will find this a standard utility fastener for equipment mounting and panel assembly work.

This cap screw is suited for light- to medium-duty fastening in both residential and commercial applications. Typical use cases include equipment bracket mounting, control panel assembly, and general mechanical assembly where an inch-series UNC thread is required. The hex head accepts standard hex keys and wrenches, making installation straightforward in tight service environments. This fastener is sold individually per package, with a minimum order quantity of 100 pieces.

Installation Notes

Installation is appropriate for any trade professional performing equipment assembly or field service work. Power down or depressurize any system before removing or installing fasteners on live equipment. Use a properly sized hex wrench or socket to avoid rounding the hex head. Apply thread-locking compound or fastener hardware per applicable equipment manufacturer specifications when vibration resistance is required.
