Value Collection 451195BR Hex Cap Screw 1-14 X 8.5 in Grade 8

Product Description

The VALUE COLLECTION 451195BR is a partially threaded hex head cap screw designed for heavy-duty fastening applications in mechanical, structural, and industrial assemblies. Built to Grade 8 steel specifications, this fastener delivers high tensile strength suited for joints that experience significant load, vibration, or shear stress. The screw measures 1-14 thread size with an 8.5-inch length under head and is finished bright and uncoated. It conforms to ASME B18.2.1 standards, making it suitable for use where dimensional consistency and load-rated fasteners are required. Machinists, millwrights, and field mechanics working with inch-series hardware will find this screw fits standard high-strength fastener applications.

This cap screw is used in stationary and mobile equipment, structural steel connections, and fabricated assemblies where a Grade 8 inch-series fastener is specified. Partial threading allows the unthreaded shank to bear shear loads in bolted joints, a common requirement in machinery frames and equipment mounts. The UNF thread standard and ASME B18.2.1 compliance make this screw appropriate for precision-fit bolted connections in both shop and field settings.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• Partially threaded shank provides shear load capacity in bolted joints
• UNF thread form with 1-14 thread specification for fine-pitch engagement
• Conforms to ASME B18.2.1 for dimensional and tolerance consistency
• Bright uncoated finish suitable for use with standard Grade 8 nuts and hardened washers
• 1-1/2 inch hex key size for use with standard heavy hex tooling

Compatibility

Designed as a standard inch-series hex head cap screw compatible with Grade 8 heavy hex nuts and hardened flat washers in UNF 1-14 thread applications per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using appropriate torque specifications for Grade 8 fasteners as defined by the applicable engineering standard or equipment manufacturer. Always use a hardened flat washer under both the head and nut when the joint design requires it. Ensure mating threads are clean and free of debris before assembly. Do not exceed rated proof load, and never reuse fasteners that have been torqued to yield.
