Value Collection R52000992 Hex Head Cap Screw 1-1/8-7 X 5 in

Product Description

The VALUE COLLECTION R52000992 is a partially threaded hex head cap screw designed for general-purpose fastening in structural and mechanical assemblies. It features a 1-1/8-7 UNC thread size with a 5-inch length measured under the head, manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance. Conforming to ASME B18.2.1 and SAE J429 standards, this fastener is suited for use by tradespeople, maintenance technicians, and contractors working on equipment supports, brackets, frames, and similar applications where inch-series fasteners are specified.

This cap screw is used across a wide range of commercial and industrial applications including HVAC equipment mounting, plumbing fixture supports, electrical enclosure installations, and general mechanical assembly. The 1-1/8-7 UNC thread configuration and partial threading make it well suited for through-bolted connections where a smooth shank section is needed for load-bearing or alignment purposes. It installs in standard hex configurations using a wrench or impact tool sized for the fastener head.

Key Features

• 1-1/8-7 UNC partially threaded shank allows smooth-shank bearing sections in through-bolt applications
• Grade 2 steel construction meets SAE J429 mechanical property requirements
• Zinc-plated finish provides basic corrosion protection in dry and mildly exposed environments
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Inch-series fastener compatible with standard UNC tooling and hardware

Compatibility

Designed as an OEM-style replacement or maintenance fastener for assemblies requiring 1-1/8-7 UNC inch-series hex head cap screws per ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using the correct wrench size for a 1-1/8-inch hex head fastener. Always ensure mating threads are clean and free of debris before assembly. Do not exceed the rated mechanical limits of Grade 2 fasteners in high-stress or safety-critical structural applications where higher grades may be specified by engineering drawings or applicable codes.
