Value Collection 88548334 Hex Cap Screw 3/8-16 X 3 in Grade 5 25pk

Product Description

The VALUE COLLECTION 88548334 is a Grade 5 steel hex head cap screw designed for general-purpose mechanical fastening in industrial, commercial, and trade applications. With a 3/8-16 UNC thread and a 3-inch length under head, this fastener is partially threaded, making it well-suited for clamping applications where thread engagement stops short of the head. The zinc-plated finish provides baseline corrosion resistance in indoor and mildly exposed environments. Each package contains 25 screws, sold in a minimum order quantity of 1 package.

This screw is used across a wide range of trade and maintenance applications, including HVAC equipment mounting, plumbing fixture assembly, electrical enclosure installation, and general mechanical assembly. The 3/8-16 UNC thread is one of the most common coarse-thread sizes in inch-system fastening, compatible with standard hex nuts, lock nuts, and threaded inserts of the same specification. Partial threading allows the unthreaded shank to bear shear loads and align mating parts before thread engagement.

Key Features

• Grade 5 steel construction for medium-strength fastening requirements
• 3/8-16 UNC coarse thread — one of the most widely used inch-system thread sizes
• 3-inch length under head accommodates thicker stack-ups and spacer assemblies
• Partially threaded shank provides shear resistance and improved part alignment
• Zinc-plated finish offers corrosion resistance in dry and mildly humid environments
• 25-piece pack reduces handling and supports small-batch job site use

Compatibility

Designed for use with standard 3/8-16 UNC hex nuts, flat washers, lock washers, and threaded inserts in inch-system mechanical assemblies.

Installation Notes

Install using a standard hex wrench, socket, or impact driver sized for a 3/8-inch hex head cap screw. Ensure mating threads are clean and free of debris before driving. Do not over-torque; refer to published Grade 5 torque specification tables for the appropriate target based on lubrication condition and joint design. Always verify thread engagement depth is sufficient for the load requirements of the application.
