Value Collection 451168BR Hex Head Cap Screw 7/8-9 X 10 in

Product Description

The VALUE COLLECTION 451168BR is a Grade 8 steel hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength and reliable clamping force. Measuring 7/8-9 thread size with a 10-inch length under the head, this fastener features a partially threaded shank and is manufactured to ASME B18.2.1 standards. The bright, uncoated finish leaves the steel bare for applications where a coating is not required or where secondary finishing will be applied. Mechanical contractors, millwrights, and industrial maintenance technicians reach for Grade 8 hardware when joint integrity under high load or vibration is the primary concern.

This cap screw is suited for structural and mechanical assemblies in industrial, commercial, and heavy equipment environments. The UNC (Unified National Coarse) thread form at 9 threads per inch is the standard for most general-purpose inch-series fastening. The long 10-inch body makes it appropriate for through-bolting thick stock, flanges, frames, or structural members where shorter fasteners cannot achieve adequate grip length. A 1-5/16-inch hex key size allows use with standard impact wrenches and hex socket sets common on job sites and in maintenance shops.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank provides full bearing contact through thick material sections
• ASME B18.2.1 dimensional compliance ensures consistent fit with standard nuts and washers
• UNC thread form for broad compatibility with inch-series hardware
• Bright, uncoated finish suitable for dry indoor environments or secondary coating
• 1-5/16-inch hex drive works with standard impact and hand socket sets

Compatibility

Designed as a standard inch-series hex head cap screw for use with 7/8-9 UNC nuts and washers in industrial, structural, and mechanical fastening applications.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a properly sized 1-5/16-inch hex socket or wrench. Apply appropriate thread lubricant or thread-locking compound per the joint design specification before torquing. Ensure mating nut and washer are rated for Grade 8 loads to maintain joint integrity. Always verify fastener length provides adequate thread engagement per applicable engineering or code requirements for the assembly.
