Value Collection 99202 Hex Head Cap Screw 7/8-9 X 5 in Grade 8

Product Description

The VALUE COLLECTION 99202 is a hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength. Sized at 7/8-9 thread with a 5-inch length under head, this fastener is manufactured from Grade 8 steel and left uncoated for use in applications where a bare steel finish is acceptable. The partial threading is consistent with standard practice for longer fasteners, allowing proper clamping force across thick material stacks. Compliance with ASME B18.2.1 and SAE J429 ensures dimensional and mechanical conformance. This fastener is installed by millwrights, pipefitters, structural mechanics, and maintenance technicians across industrial and commercial environments.

This cap screw suits structural, mechanical, and equipment assembly applications where a UNC inch-series thread and Grade 8 strength rating are specified. Typical uses include machine frames, heavy equipment mounting, steel fabrication, and maintenance repair operations. The 7/8-9 UNC thread form is widely used in North American industrial specifications. The partial threading accommodates clearance holes and longer grip lengths common in bolted joint designs.

Key Features

• Grade 8 steel construction meets SAE J429 mechanical property requirements for high-strength fasteners
• 7/8-9 UNC thread form in inch-series measurement system
• 5-inch length under head accommodates thick material stacks and long grip lengths
• Partial threading for proper clamping load distribution in clearance-hole assemblies
• Uncoated finish suitable for applications where coating is applied post-installation or not required
• Conforms to ASME B18.2.1 dimensional standard

Compatibility

Designed as an OEM-style replacement or direct-use Grade 8 hex head cap screw for industrial, structural, and mechanical assemblies requiring a 7/8-9 UNC thread and 5-inch grip length.

Installation Notes

Installation should be performed by qualified millwrights, mechanics, or maintenance technicians familiar with bolted joint specifications. Always verify thread engagement depth and torque requirements per the applicable engineering specification or equipment service manual before tightening. Use appropriate hand tools or powered equipment rated for 7/8-inch fasteners. Do not exceed specified torque values or substitute a lower-grade fastener in high-load joint applications.
