Value Collection R52001102 Hex Head Cap Screw Grade 5

Product Description

The VALUE COLLECTION R52001102 is a partially threaded hex head cap screw built to ASME B18.2.1 and SAE J429 standards. It features a 1-1/2-6 UNC thread size and measures 5-1/2 inches under the head. Constructed from Grade 5 steel with a zinc-plated finish for corrosion resistance, this fastener is suited for heavy-duty structural and mechanical assembly applications. The partial threading allows for load-bearing clamping across thick material sections. At 3.65 pounds, it is a substantial fastener intended for industrial, commercial, or trade installation work requiring high-tensile bolted connections.

This hex head cap screw is used in structural assemblies, equipment mounting, and mechanical connections where high-strength inch-series fasteners are required. The 1-1/2-6 UNC coarse thread is a standard size in heavy-duty fabrication, HVAC equipment anchoring, mechanical base-plate mounting, and general trade construction. The zinc-plated finish provides a baseline level of corrosion protection suitable for indoor and controlled-environment installations. It is sold individually and is appropriate for projects specifying Grade 5 steel fasteners per SAE J429 requirements.

Key Features

• 1-1/2-6 UNC coarse thread for high-load bolted connections
• 5-1/2 inches under the head — accommodates thick material stack-ups
• Grade 5 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish for baseline corrosion resistance
• Partially threaded shank for improved clamping and shear performance
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application specifying a 1-1/2-6 UNC x 5-1/2-inch Grade 5 partially threaded fastener per ASME B18.2.1 and SAE J429.

Installation Notes

Installation should be performed by a qualified mechanic, ironworker, or trade professional familiar with high-strength fastener procedures. Always ensure mating threads are clean and free of debris before assembly. Apply torque using a calibrated torque wrench in accordance with the applicable structural or mechanical specification for Grade 5 fasteners. Do not mix metric and inch-series hardware in the same joint.
