Value Collection 451012BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451012BR is a partially threaded hex head cap screw designed for heavy-duty fastening applications. Built to Grade 8 steel specifications, this fastener delivers high tensile strength suitable for demanding structural and mechanical assemblies. It measures 1-1/8-7 thread size with a 9-inch length under head and is finished bright and uncoated, meeting ASME B18.2.1 standards. The uncoated finish is appropriate for indoor or dry-environment installations where corrosion resistance is not a primary requirement. This screw weighs 2.86 pounds and is driven with a 1-11/16-inch hex key. It is sold individually and is the right choice for contractors and mechanics working with high-load bolted connections.

This hex head cap screw is suited for industrial, commercial, and heavy equipment assembly applications where Grade 8 tensile strength is specified. The UNC thread form and partial threading make it appropriate for bolted joints where the shank bears shear loads or where the grip length must pass through a clearance hole before engaging a nut or tapped hole. Typical users include millwrights, structural mechanics, and maintenance technicians working on machinery, steel fabrication, and structural connections.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1-1/8-7 UNC thread with 9-inch length under head for deep grip applications
• Partially threaded shank to handle shear loads and maintain grip length integrity
• Bright uncoated finish conforming to ASME B18.2.1
• 1-11/16-inch hex drive for standard wrench engagement
• Weighs 2.86 pounds for a single-piece fastener of this size class

Compatibility

Designed as an OEM-style replacement or new-installation fastener for applications specifying a 1-1/8-7 UNC Grade 8 hex head cap screw per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic or trades professional familiar with high-strength fastener procedures. Always clean and inspect the mating threads before installation, and confirm the tapped hole or nut grade is compatible with Grade 8 fasteners. Use a calibrated torque wrench and follow the torque values specified by the equipment manufacturer or applicable structural code. Do not substitute a lower-grade fastener in a Grade 8-specified joint.
