Value Collection 451060BR Hex Head Cap Screw Grade 8

Product Description

The VALUE COLLECTION 451060BR is a fully threaded hex head cap screw designed for heavy-duty fastening applications. It measures 1-1/2-6 thread size with a 4-1/2-inch length under the head, machined to Grade 8 steel for high tensile strength and resistance to shear and fatigue. The uncoated bright finish means it ships ready for use or can be finished on-site to match project requirements. Conforming to ASME B18.2.1, this fastener meets recognized dimensional and mechanical standards for inch-series hex cap screws. It is installed with a 2-1/4-inch hex key or wrench and is suited for structural, mechanical, and industrial assemblies where a high-strength UNC fastener is required.

This cap screw is appropriate for heavy industrial, commercial, and structural applications where Grade 8 fastener specifications are called out on engineering drawings or assembly specs. Typical uses include machinery mounts, structural steel connections, equipment frames, and other bolted joints requiring high clamping force. The fully threaded shank allows maximum thread engagement across the full 4-1/2-inch length, which is useful in through-bolted or tapped-hole configurations. Mechanical contractors, millwrights, pipefitters, and general industrial tradespeople routinely install fasteners of this class.

Key Features

• Grade 8 steel construction for high tensile and proof load ratings
• Fully threaded shank along the entire 4-1/2-inch length under head
• 1-1/2-6 UNC thread form per ASME B18.2.1 dimensional standard
• Bright uncoated finish — no post-process coating to interfere with torque-tension relationship
• 2-1/4-inch hex drive compatible with standard industrial hex wrenches and impact sockets
• Sold individually — no minimum multi-pack required

Compatibility

Designed for use in any application specifying a 1-1/2-6 UNC Grade 8 hex head cap screw per ASME B18.2.1 with full threading.

Installation Notes

Installation should be performed by a qualified tradesperson using a calibrated torque wrench or hydraulic torque tool appropriate for large-diameter fasteners. Always verify mating thread condition and hole alignment before driving. Grade 8 fasteners must be torqued to the value specified by the equipment or structure manufacturer — do not substitute generic torque tables without engineering authorization. De-energize and lock out any equipment before replacing or tightening fasteners in mechanical assemblies.
