Value Collection 11276CH2 Hex Head Cap Screw 1-1/8-7

Product Description

The VALUE COLLECTION 11276CH2 is a partially threaded hex head cap screw designed for heavy fastening applications across mechanical, structural, and industrial assembly work. It carries a 1-1/8-7 UNC thread and measures 4-3/4 inches under the head. The fastener is manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance. It meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards. Installation requires a 1-11/16-inch hex key or socket. The partial thread design is suited for clamping applications where a shank grip length is needed between the bearing surface and the threaded engagement zone.

This cap screw is used in general-purpose industrial and mechanical assemblies where an inch-series UNC fastener in a large diameter is required. Typical applications include equipment frames, structural connections, machinery mounting, and heavy-duty fixture work. It is installed by maintenance technicians, millwrights, pipefitters, and general tradespeople working on equipment that requires a robust 1-1/8-inch diameter fastener with partial thread engagement.

Key Features

• 1-1/8-7 UNC thread form — inch-series coarse thread for broad hardware compatibility
• Partial threading provides a full shank grip length between bearing surface and thread engagement
• Grade 2 steel construction meets SAE J429 mechanical requirements
• Zinc-plated finish offers basic corrosion resistance for general indoor and light-duty outdoor use
• Conforms to ASME B18.2.1 dimensional standards for hex head cap screws
• Requires 1-11/16-inch hex socket or wrench for installation

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use in any application requiring a 1-1/8-7 thread size and 4-3/4-inch length under head.

Installation Notes

Installation is performed by qualified tradespeople using a 1-11/16-inch socket or hex wrench. Verify that mating threads are clean and free of debris before installation. Do not exceed the mechanical rating of Grade 2 steel in high-stress or safety-critical structural connections where a higher grade fastener may be required. Follow applicable industry standards and engineering specifications for torque requirements on the specific application.
