Value Collection 451053PR Hex Head Cap Screw 1/4-20 X 8 in

Product Description

The VALUE COLLECTION 451053PR is a Grade 8 steel hex head cap screw with a 1/4-20 UNC thread and an 8-inch length under head. It features partial threading and a bright, uncoated finish. Grade 8 fasteners are heat-treated to deliver high tensile and proof load strength, making them appropriate for demanding structural and mechanical assemblies. This screw is manufactured to ASME B18.2.1 standards, ensuring consistent dimensional accuracy for professional installation. Mechanics, millwrights, and maintenance technicians working on heavy equipment, machinery mounts, or structural steel connections will find this fastener suitable for high-load applications.

This cap screw is used in industrial, commercial, and heavy-duty mechanical applications where a Grade 8 fastener is specified. The partial threading allows the unthreaded shank to bear shear loads in bolted joints, a common requirement in equipment frames, brackets, and structural connections. It is sold individually with a minimum order quantity of 10 pieces, making it practical for service trucks and shop inventory replenishment.

Key Features

• Grade 8 steel construction for high tensile strength in demanding assemblies
• 1/4-20 UNC thread form with partial threading for shear-load bearing applications
• 8-inch length under head accommodates deep-stack or long-reach fastening needs
• Bright, uncoated finish suitable for use where coatings are not required or specified
• Manufactured to ASME B18.2.1 dimensional standards for consistent fitment
• 7/16-inch hex key drive size for standard wrench and socket compatibility

Compatibility

Designed as an OEM-style replacement or service fastener for any application requiring a 1/4-20 UNC, Grade 8, partially threaded hex head cap screw with an 8-inch length under head per ASME B18.2.1.

Installation Notes

Installation is performed with a 7/16-inch open-end wrench, combination wrench, or socket. Always de-energize and lock out equipment before fastener service on mechanical assemblies. Apply torque values specified by the equipment manufacturer for 1/4-20 Grade 8 fasteners. Inspect mating threads for damage or contamination before assembly.
