Value Collection 451019BR Hex Cap Screw 1-1/8-12 X 5 in Grade 8

Product Description

The VALUE COLLECTION 451019BR is a Grade 8 steel hex head cap screw designed for high-strength fastening applications. It features a 1-1/8-12 unified fine thread (UNF) and measures 5 inches under the head with partial threading. Grade 8 steel construction delivers high tensile and proof load ratings suited for demanding mechanical and structural connections. The bright, uncoated finish is standard for applications where corrosion protection is not required or where secondary coating will be applied in the field. This fastener conforms to ASME B18.2.1 dimensional standards.

This cap screw is appropriate for heavy equipment assembly, industrial machinery, structural steel fabrication, and other applications requiring a fine-thread, high-strength fastener in larger diameter sizes. The partially threaded shank provides a bearing surface that resists shear loads in bolted joint applications. Machinists, millwrights, maintenance technicians, and general industrial assemblers typically use fasteners of this specification.

Key Features

• Grade 8 steel construction for high-strength bolted joint applications
• 1-1/8-12 UNF thread form for fine-thread engagement and vibration resistance
• Partially threaded shank provides shear resistance and precise clamping
• Bright, uncoated finish meets ASME B18.2.1 dimensional requirements
• Hex key size of 1-11/16 inches for standard wrench fitment

Compatibility

Designed as a standard ASME B18.2.1 inch-series hex head cap screw, compatible with any 1-1/8-12 UNF tapped hole or nut in heavy mechanical, structural, or industrial assembly applications.

Installation Notes

Installation requires a wrench or socket sized for a 1-11/16 inch hex. Power down and de-energize any associated equipment before fastener replacement on machinery. Apply thread lubricant or anti-seize compound only where specified by the equipment manufacturer. Follow applicable industry torque specifications for Grade 8 fasteners at this diameter as defined by the joint design engineer or equipment OEM documentation.
