Value Collection A997150 Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION A997150 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw features a 1-8 UNC thread size and a 10-inch length under head, making it suited for applications requiring deep thread engagement through thick material. The 3/4-inch hex drive accepts a standard hex key or Allen wrench for installation and removal. Manufactured from alloy steel with a black oxide finish, the A997150 delivers solid corrosion resistance in controlled environments and is partially threaded along its shank. Licensed tradespeople, machinists, and maintenance technicians are the typical installers for this fastener type.

This screw is used in heavy mechanical assemblies, structural steel connections, machine tool fixtures, and industrial equipment where a recessed-drive, high-strength fastener is required. The 1-8 UNC coarse thread is compatible with standard inch-series tapped holes and nuts. The partial threading leaves a smooth shank section useful for precise alignment and shear-load applications. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming its suitability for demanding load-bearing applications.

Key Features

• 3/4-inch hex socket drive for use with standard hex keys or Allen wrenches
• Partially threaded shank for alignment and shear-load applications
• Alloy steel construction with black oxide coating for corrosion resistance in controlled environments
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard replacement or new-installation hex socket cap screw for 1-8 UNC tapped holes in industrial machinery, structural steel assemblies, and heavy mechanical equipment.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or maintenance technician. Verify that the mating tapped hole is clean, undamaged, and properly sized for 1-8 UNC threading before installation. Apply an appropriate thread lubricant or thread-locking compound as required by the application. Use a calibrated torque wrench with the correct 3/4-inch hex bit to achieve proper clamping force per the assembly specification.
