Value Collection 99227 Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 99227 is a partially threaded hex head cap screw built to Grade 8 steel specifications for high-strength fastening applications. Measuring 1-8 thread size by 7 inches in length under head, this screw is manufactured to ASME B18.2.1 standards and features a Unified National Coarse (UNC) thread form. The uncoated finish means the steel surface is bare, which is typical for applications where secondary coating, plating, or lubrication will be applied in the field. Grade 8 designation indicates a high-tensile-strength fastener suitable for heavy-duty mechanical assemblies. Installation requires a standard hex wrench or socket driver sized for a 1-8 bolt head.

This cap screw is suited for structural and mechanical fastening in industrial, commercial, and trade applications where Grade 8 strength is specified. Partially threaded shanks are commonly used when a smooth grip-length section is needed to prevent thread engagement in a structural member or to allow controlled clamping load distribution. Typical install scenarios include equipment mounting, machinery frames, flanged connections, and structural steel assemblies. Sold in a package quantity of 10.

Key Features

• Grade 8 steel construction meets high-tensile-strength requirements for heavy-duty fastening
• Partially threaded shank provides a smooth grip length for controlled clamping applications
• UNC thread form per ASME B18.2.1 standard ensures dimensional consistency and interchangeability
• Uncoated finish suitable for field-applied coatings, platings, or lubrication
• Package quantity of 10 units per order

Compatibility

Designed as a standard-dimension replacement or service fastener for any assembly specifying a 1-8 UNC x 7 inch partially threaded Grade 8 hex head cap screw per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with fastener torque specifications for Grade 8 hardware. Always consult the equipment or structural assembly specification sheet for the correct torque value — do not estimate torque on high-strength fasteners. Ensure mating threads are clean and free of debris before installation. Applying a thread lubricant or anti-seize compound will affect torque values and should only be done when specified by the assembly documentation.
