Value Collection 403250BR Hex Cap Screw 5/8-11 X 5-1/2 in Grade 2

Product Description

The VALUE COLLECTION 403250BR is a partially threaded hex head cap screw designed for general-purpose fastening in structural, mechanical, and equipment-assembly applications. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 5/8-11 thread size with a 5-1/2 inch length under the head. The UNC thread standard ensures broad compatibility with standard tapped holes and nuts. The partial threading allows the unthreaded shank to bear shear loads in bolted joints, making it appropriate for clamped assemblies where full threading is not required. Installation uses a 15/16 inch hex key or wrench drive.

This screw is suited for maintenance, fabrication, and assembly work across industrial, commercial, and trade settings. Typical applications include equipment mounting, structural connections, and machinery repair where a heavy hex fastener with zinc corrosion protection is specified. The zinc plating provides a baseline level of corrosion resistance appropriate for dry indoor and moderately protected environments. Sold individually with a minimum order quantity of 10 units.

Key Features

• 5/8-11 UNC thread size for compatibility with standard hex nuts and tapped holes
• 5-1/2 inch length under head accommodates thicker clamped material stacks
• Partial threading allows shank to carry shear loads in bolted assemblies
• Grade 2 steel construction meets general-purpose strength requirements
• Zinc-plated finish provides corrosion protection in dry or semi-protected environments
• 15/16 inch hex drive fits standard open-end, box, and socket wrenches

Compatibility

Designed for use with standard 5/8-11 UNC hex nuts, flat washers, and lock washers in general-purpose bolted assemblies across industrial and trade applications.

Installation Notes

Installation is performed with a 15/16 inch open-end, combination, or socket wrench. Ensure mating threads are clean and free of debris before driving the fastener. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards for Grade 2 fasteners at this diameter. Do not use impact tools at speeds that may cause thread galling or exceed Grade 2 material limits.
