Value Collection -97247-1 Hex Head Cap Screw 1-1/4-7

Product Description

The VALUE COLLECTION -97247-1 is a hex head cap screw sized 1-1/4-7 UNC with a 5-1/2-inch length under head. Made from Grade 5 steel with no surface coating, it delivers dependable tensile strength for general industrial and mechanical fastening applications. The partial thread design concentrates grip in the threaded zone while leaving the shank smooth for shear-load and alignment situations. Machinists, millwrights, maintenance mechanics, and structural assembly technicians regularly specify this fastener class for medium-to-heavy duty bolted joints. Compliance with ASME B18.2.1 ensures dimensional consistency for fit-critical assemblies.

This cap screw is suited for industrial machinery assembly, structural steel connections, heavy equipment maintenance, and general fabrication work where a unified coarse thread fastener in a large diameter is required. The 1-1/4-7 UNC thread pitch is a standard designation widely used in North American manufacturing and maintenance environments. The uncoated finish makes it compatible with applications where post-installation coating, galvanizing, or plating will be applied by the end user or installer. Sold in a package quantity of 5.

Key Features

• Partially threaded shank accommodates shear loads and aids bolt alignment in clearance holes
• Uncoated finish allows field-applied surface treatments after installation
• Meets ASME B18.2.1 dimensional standard for dimensional consistency in fit-critical assemblies
• Sold in a package of 5 with a minimum order quantity of 1

Compatibility

Designed as a standard UNC hex head cap screw per ASME B18.2.1, suitable for use with any 1-1/4-7 UNC threaded hole or nut in industrial, structural, or mechanical assemblies.

Installation Notes

Installation is performed by qualified mechanics or millwrights using appropriate hand or power tools sized for a 1-1/4-inch hex head fastener. Follow applicable torque specifications from the equipment manufacturer or a recognized fastener torque standard for Grade 5 fasteners of this diameter. Ensure mating threads are clean and free of damage before installation. Do not mix inch and metric hardware in the same threaded connection.
