Value Collection 99208 Hex Head Cap Screw 7/8-9 X 8 in Grade 8

Product Description

The VALUE COLLECTION 99208 is a Grade 8 steel hex head cap screw designed for high-strength bolted connections in demanding mechanical and structural applications. Measuring 7/8-9 thread size with an 8-inch length under head, this fastener features a Unified National Coarse (UNC) thread form and is partially threaded to provide a smooth shank section for shear-load applications. The uncoated finish means the fastener ships in bare steel and is ready for immediate installation or field finishing. Meets ASME B18.2.1 and SAE J429 standards, confirming dimensional accuracy and mechanical grade compliance.

This screw is suited for heavy equipment assembly, structural steel connections, industrial machinery mounting, and other applications where Grade 8 tensile strength is required. The 7/8-9 coarse thread engages quickly in tapped holes or with standard hex nuts and hardened washers. Sold in a package quantity of 5, it is a practical option for maintenance shops, millwrights, and mechanical contractors who need certified high-strength fasteners without sourcing full bulk quantities.

Key Features

• Grade 8 steel construction for high-strength, high-torque bolted joints
• 7/8-9 UNC thread form for broad compatibility with standard tapped holes and hex nuts
• 8-inch length under head with partial threading to support shear-load installations
• Uncoated bare steel finish — field-paintable or coatable as required
• Meets ASME B18.2.1 and SAE J429 dimensional and mechanical standards
• Sold in a package of 5 to support small-lot maintenance and repair jobs

Compatibility

Designed as a standard 7/8-9 UNC hex head cap screw for use with any application requiring Grade 8 fasteners conforming to ASME B18.2.1 and SAE J429 specifications.

Installation Notes

Installation of Grade 8 fasteners is typically performed by millwrights, mechanical contractors, or experienced maintenance technicians. Always use hardened flat washers under both the head and nut when required by the joint design. Tighten to the torque specification defined by the joint engineer or equipment OEM — do not estimate torque without a calibrated torque wrench. Inspect threads for damage before installation; damaged threads on Grade 8 hardware should not be used in structural or high-load applications.
