Value Collection 451220BR Hex Head Cap Screw 3/4-10x11 Grade 8

Product Description

The VALUE COLLECTION 451220BR is a 3/4-10 hex head cap screw measuring 11 inches in length under the head, manufactured from Grade 8 steel with a bright uncoated finish. Grade 8 steel provides high tensile strength suitable for demanding structural and mechanical fastening applications. The partially threaded shank follows UNC thread standards and conforms to ASME B18.2.1 dimensional specifications. This fastener is driven with a 1-1/8-inch hex key or wrench. It weighs 1.45 pounds and is sold individually. Mechanics, millwrights, ironworkers, and general contractors typically install this type of fastener in heavy-duty assemblies.

This cap screw is suited for structural steel connections, heavy equipment frames, agricultural machinery, and industrial fabrication where high-clamp-load fasteners are required. The partially threaded shank is appropriate for applications that require a smooth bearing surface in the grip area, such as bolted joint assemblies where shear loads are present. It is commonly used in both shop fabrication and field installation settings where Grade 8 strength class is specified by design.

Key Features

• Grade 8 steel construction for high tensile and proof-load strength
• 3/4-10 UNC thread size with partial threading along the shank
• 11-inch length under head for deep-grip structural applications
• Bright uncoated finish — suitable for use with separately applied coatings or in dry indoor environments
• Conforms to ASME B18.2.1 dimensional standard
• 1-1/8-inch hex drive size compatible with standard hex sockets and open-end wrenches

Compatibility

Designed as an OEM-style replacement or direct-install fastener for any assembly specifying a 3/4-10 UNC hex head cap screw at 11 inches length under head, Grade 8 steel, per ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or structural ironworker following applicable engineering specifications and torque requirements for Grade 8 fasteners. Always clean and inspect mating threads before installation. Use a calibrated torque wrench and apply the torque value specified by the joint design engineer — do not estimate torque by feel on high-strength fasteners. Follow applicable codes such as AISC or ASME standards for structural bolting procedures.
