Value Collection 99112 Hex Head Cap Screw 1/2-13 X 3 in Grade 8

Product Description

The VALUE COLLECTION 99112 is a Grade 8 steel hex head cap screw with a 1/2-13 UNC thread and a 3-inch length under head. It is partially threaded and left uncoated with a bright finish. Grade 8 designation indicates high tensile strength, making this fastener suited for heavy-duty bolted connections in mechanical, structural, and industrial assemblies. It conforms to ASME B18.2.1 dimensional standards. Machinists, millwrights, maintenance technicians, and general contractors install this type of fastener where high-strength, inch-series bolting is required. This SKU is sold in a pack of 25.

This hex head cap screw is used across a wide range of commercial, industrial, and mechanical service applications where a standard UNC 1/2-13 thread pattern is specified. Typical uses include equipment mounting, structural steel connections, machinery assembly, and maintenance repairs. The partially threaded shank allows for a bearing-surface grip in bolted joint applications where full thread engagement is not needed or desired. The bright uncoated finish is appropriate for indoor or protected environments where corrosion exposure is limited.

Key Features

• Grade 8 steel construction for high tensile strength in demanding bolted joint applications
• 1/2-13 UNC thread standard provides broad compatibility with standard inch-series nuts and tapped holes
• Partially threaded shank supports proper grip length in structural and mechanical connections
• Bright uncoated finish meets ASME B18.2.1 dimensional requirements
• Sold in a 25-piece pack to support batch repairs and production assembly work

Compatibility

Designed for use with standard 1/2-13 UNC inch-series nuts, washers, and tapped holes conforming to ASME B18.2.1 specifications in industrial, mechanical, and structural fastening applications.

Installation Notes

Installation is performed by machinists, maintenance technicians, or structural tradespeople using standard hex wrenches or impact tools sized for a 3/4-inch hex head. Always verify thread engagement depth and joint material grade before final torque. Do not mix Grade 8 fasteners with lower-grade nuts or tapped holes rated below the fastener's tensile class. Follow applicable ASME or facility engineering standards for torque and joint preload requirements.
