Value Collection 88548128 Hex Cap Screw 1/4-20 X 1-1/2 in Grade 5 50pk

Product Description

The VALUE COLLECTION 88548128 is a 1/4-20 x 1-1/2 inch hex head cap screw designed for general-purpose fastening in trade and industrial applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener delivers reliable tensile strength and corrosion resistance in moderate-exposure environments. The partial threading along the shank provides a grip-bearing surface for clamping applications where a fully threaded bolt would be less effective. The UNC (Unified National Coarse) thread standard ensures compatibility with standard 1/4-20 tapped holes and nuts. Electricians, HVAC technicians, plumbers, and general contractors use this fastener daily for panel mounting, equipment attachment, and structural connections. Each package contains 50 pieces.

This hex head cap screw is suited for residential and light commercial applications involving metal-to-metal fastening, equipment mounting, and component assembly. The 1/4-20 UNC thread size is one of the most common fastener sizes encountered in HVAC cabinet assembly, electrical panel installation, plumbing fixture mounting, and general mechanical work. The zinc plating provides a baseline level of corrosion protection appropriate for indoor and sheltered outdoor installations. Length is measured under the head at 1-1/2 inches, which accommodates typical bracket and panel stack thicknesses encountered in trade work.

Key Features

• Grade 5 steel construction provides higher tensile strength than standard Grade 2 fasteners
• Zinc-plated finish offers corrosion resistance for indoor and sheltered installations
• Partial threading allows for a shank grip zone, improving clamping performance
• 1/4-20 UNC thread standard fits the most widely used tapped holes and hardware in trade applications
• 1-1/2 inch length under head suits typical panel, bracket, and equipment mounting thicknesses
• 50-piece packaging keeps jobsite inventory efficient for repetitive fastening tasks

Compatibility

Designed for use in any application requiring a standard 1/4-20 UNC hex head cap screw in Grade 5 steel with a zinc finish and partial threading.

Installation Notes

Install using a standard hex wrench or socket drive sized for a 1/4-20 hex head fastener. Always de-energize electrical equipment and shut off system power before fastening near live components. Do not exceed the rated tensile strength of Grade 5 hardware by applying impact tools at torque levels intended for higher-grade fasteners. Follow applicable NEC or mechanical code requirements when using fasteners in code-governed assemblies.
