Value Collection 592256BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592256BR is a hex socket cap screw designed for high-strength fastening applications requiring precise torque control. It features a 7/8-9 UNC thread with an 8-inch length under head and a 3/4-inch hex drive socket. The screw is partially threaded and constructed from 18-8 austenitic stainless steel (Grade A2), offering solid corrosion resistance in wet, chemical, or outdoor environments. It is manufactured to ASME/ANSI B18.3 and ASTM F837 standards. Machinists, millwrights, maintenance technicians, and industrial tradespeople install this fastener in structural assemblies, machinery, and equipment where a recessed drive and reliable clamp load are required.

This cap screw is suited for industrial and commercial applications including machinery frames, structural steel assemblies, pump mounts, and equipment enclosures. The 18-8 stainless steel construction makes it appropriate for environments with moisture exposure or mild chemical contact. The partial thread design allows for improved shank strength and controlled engagement in blind or through-hole applications. It is sold individually and is appropriate for both new installation and maintenance repair operations.

Key Features

• 7/8-9 UNC thread size for standard inch-series fastening applications
• 8-inch length under head provides deep reach in thick or stacked assemblies
• 3/4-inch hex socket drive for use with standard hex keys or socket drivers
• Partially threaded shank improves tensile strength and reduces stress concentration
• 18-8 austenitic stainless steel (Grade A2) delivers corrosion resistance without coatings
• Manufactured to ASME/ANSI B18.3 and ASTM F837 dimensional and material standards

Compatibility

Designed as an OEM-style and MRO replacement hex socket cap screw for standard 7/8-9 UNC tapped holes in industrial machinery, structural assemblies, and equipment frames requiring an 8-inch fastener length.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a calibrated torque wrench and the appropriate 3/4-inch hex key or socket. Ensure the tapped hole is clean and free of debris before installation. Follow applicable ASME standards and equipment manufacturer specifications for torque values. Mixing stainless steel fasteners with dissimilar metals in corrosive environments may require anti-galling compound to prevent thread seizure.
