Value Collection R63146142 Hex Head Cap Screw 3/4-10 X 9 in

Product Description

The VALUE COLLECTION R63146142 is a 3/4-10 hex head cap screw machined from 18-8 stainless steel and left uncoated for a clean, corrosion-resistant finish. At 9 inches under the head with partial threading and a Unified National Coarse (UNC) thread form, this fastener is suited for heavy structural and mechanical assembly work where both clamping strength and corrosion resistance are required. The 3/4-10 designation indicates a 3/4-inch nominal diameter with 10 threads per inch. Tradespeople and maintenance professionals reach for partially threaded cap screws when the unthreaded shank needs to bear shear load or align mating components before full engagement.

This cap screw is commonly used in industrial machinery, HVAC equipment frames, structural steel connections, plumbing support structures, and marine or outdoor installations where stainless steel grade 18-8 provides adequate resistance to moisture and mild chemical exposure. The hex drive head accommodates standard 6-point sockets and open-end wrenches found in any trade shop. Partial threading is standard practice on longer fasteners where only the grip length nearest the nut carries the load.

Key Features

• 3/4-10 UNC thread form for broad tooling compatibility
• 9-inch length under head suits deep-grip structural assemblies
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Partially threaded shank handles shear loads and aids alignment during assembly
• Uncoated finish maintains dimensional accuracy without added coating thickness
• Hex head accepts standard 6-point sockets and open-end wrenches

Compatibility

Designed as a standard 3/4-10 UNC hex head cap screw compatible with any application specifying an 18-8 stainless steel partially threaded fastener in that thread size and length.

Installation Notes

Installation is performed by maintenance mechanics, millwrights, and trade professionals using appropriate 6-point sockets or wrenches rated for the fastener size. Always verify that mating tapped holes or nuts are also 3/4-10 UNC before driving the fastener. Do not use an impact driver at full speed on stainless steel fasteners, as galling of the threads can occur. Follow applicable torque specifications from the equipment manufacturer or relevant structural standard for the application.
