Value Collection 592485BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592485BR is a hex socket cap screw designed for structural and mechanical fastening applications requiring corrosion-resistant hardware. This screw features a 7/8-9 UNC thread form, a 5-inch length under head, and a 3/4-inch hex socket drive. Manufactured from 18-8 austenitic stainless steel (Material Grade A2), it meets ASME/ANSI B18.3 and ASTM F837 fastener standards. The bright, uncoated finish is suitable for environments where bare stainless steel is specified. Partially threaded along its shank, it provides a grip zone that is useful in clamped-joint and shear-load applications. Licensed trades and industrial maintenance technicians install this type of hardware across a wide range of mechanical and structural assemblies.

This cap screw is used in commercial and industrial applications where high-strength, corrosion-resistant threaded fasteners are required. Typical installation scenarios include machinery assembly, pump and bracket mounting, structural steel connections, and food-service or marine equipment where stainless steel hardware is specified by design or code. The partial threading suits applications where a full bearing shank is needed through one or more members before thread engagement begins in the tapped hole or nut.

Key Features

• 7/8-9 UNC thread size for standard inch-series tapped holes and nuts
• 5-inch length under head with partial threading for grip-zone shear applications
• 3/4-inch hex socket drive for high-torque installation with a standard hex key or socket tool
• 18-8 austenitic stainless steel, Material Grade A2, for corrosion resistance in wet or chemically active environments
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards
• Bright, uncoated finish — no plating or coating to interfere with torque-tension calculations

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 7/8-9 UNC partially threaded fastener conforming to ASME/ANSI B18.3 and ASTM F837.

Installation Notes

Installation requires a 3/4-inch hex key or socket drive rated for the applied torque. Power down or de-energize any adjacent equipment before fastener installation in mechanical assemblies. Apply fastener torque values per the applicable engineering specification for 18-8 stainless steel hardware — do not rely on carbon steel torque tables, as stainless galling risk requires appropriate lubrication or anti-seize compound on the threads. Follow applicable codes and project specifications for structural or pressure-boundary applications.
