Value Collection 451194BR Hex Head Cap Screw 1-14x8 Grade 8

Product Description

The VALUE COLLECTION 451194BR is a Grade 8 steel hex head cap screw with a 1-14 UNF thread size and an 8-inch length under head. It is partially threaded and left uncoated with a bright finish. This fastener is manufactured to ASME B18.2.1 standards, making it suitable for high-strength bolted assemblies in industrial, mechanical, and structural applications. Installation is performed by millwrights, maintenance technicians, and general mechanics working on heavy equipment, machinery mounts, and fabricated steel structures. The 1-1/2-inch hex key drive size is compatible with standard industrial impact and hand tools.

This cap screw is suited for high-load applications requiring a coarse-to-fine thread pitch, specifically UNF 1-14. Partially threaded shanks provide a stronger grip in thick material applications where full thread engagement is not required. Common install scenarios include machinery frames, structural steel connections, flanged joints, and heavy fabrication work. The uncoated bright finish means it is best used in dry or controlled environments or where a coating will be applied after assembly.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 1-14 UNF thread form per ASME B18.2.1 standard
• Partially threaded shank suited for thick-material and structural connections
• Bright uncoated finish for bare-steel or post-assembly coating applications
• 1-1/2-inch hex drive compatible with standard industrial tooling
• 8-inch length under head for deep or stacked-material fastening

Compatibility

Designed as a standard-dimension Grade 8 hex head cap screw per ASME B18.2.1, suitable for any application requiring a 1-14 UNF partially threaded fastener with an 8-inch length under head.

Installation Notes

Installation is typically performed by qualified mechanics, millwrights, or structural fabricators using appropriate torque tooling rated for Grade 8 fasteners. De-energize and lock out any machinery before installing or removing fasteners in live equipment. Apply thread lubricant or anti-seize only if the joint specification calls for it, as dry torque values differ from lubricated values. Follow applicable structural or mechanical codes for torque requirements appropriate to the joint design.
