Value Collection 99254 Hex Head Cap Screw Grade 8 Steel

Product Description

The VALUE COLLECTION 99254 is a partially threaded hex head cap screw designed for heavy-duty fastening applications requiring high tensile strength. Manufactured from Grade 8 steel with an uncoated finish, this fastener measures 1-1/4-7 UNC thread size with a 9-inch length under the head. It conforms to ASME B18.2.1 dimensional standards, making it a reliable choice for structural and mechanical assemblies where precise thread engagement and load capacity are critical. Installation is performed by maintenance technicians, millwrights, and mechanical contractors working on equipment, frames, and structural connections.

This cap screw is suited for industrial, commercial, and heavy equipment applications where Grade 8 steel strength is required. The partial threading allows for a smooth shank section that resists shear loading along the grip length, a common requirement in bolted joint assemblies. The 1-1/4-7 UNC coarse thread pattern provides dependable engagement in standard tapped holes and with compatible nuts. Sold in a package quantity of 2 per order.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1-1/4-7 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• Partially threaded shank resists shear forces across the grip length
• Uncoated finish — suitable for use where additional coatings or platings will be applied on-site
• Conforms to ASME B18.2.1 dimensional standard
• Package quantity of 2 per order

Compatibility

Designed for use in standard UNC tapped holes or with 1-1/4-7 hex nuts in structural, industrial, and heavy mechanical assembly applications requiring ASME B18.2.1 compliant fasteners.

Installation Notes

Installation should be performed by qualified mechanical or maintenance personnel following applicable torque specifications for Grade 8 fasteners as defined by engineering or job specifications. Ensure mating threads and bearing surfaces are clean and free of debris before assembly. Use of a calibrated torque wrench is standard practice for critical joint applications. Do not substitute Grade 8 fasteners with lower-grade hardware in load-bearing or structural connections.
