Value Collection 592252BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592252BR is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and structural assemblies. It features a 7/8-9 UNC thread size with 6-1/2 inches of length under the head and a 3/4-inch hex drive. The screw is partially threaded, which provides a smooth shank section for shear load applications. Constructed from 18-8 austenitic stainless steel (Grade A2), it resists corrosion in wet or chemically active environments. The bright, uncoated finish meets ASME/ANSI B18.3 and ASTM F837 standards. This fastener is installed by machinists, millwrights, maintenance technicians, and general contractors requiring a reliable, corrosion-resistant cap screw.

This cap screw is suited for use in general industrial machinery, fabricated steel assemblies, pump housings, and equipment requiring corrosion-resistant fasteners. The partial threading makes it well-suited for through-bolted joints where shank bearing strength is needed. The 7/8-9 UNC coarse thread pattern provides strong clamping force and is compatible with standard UNC tapped holes or hex nuts of matching thread specification. It is commonly used in both indoor and outdoor environments where moisture or chemical exposure is a concern.

Key Features

• 7/8-9 UNC coarse thread for strong clamping force and compatibility with standard UNC tapped holes
• 6-1/2 inches length under head for deep fastening applications
• Partially threaded shank provides shear load resistance in through-bolt applications
• 18-8 austenitic stainless steel (Grade A2) offers corrosion resistance in wet and chemically active environments
• Bright, uncoated finish meets ASME/ANSI B18.3 and ASTM F837 standards
• 3/4-inch hex drive accommodates standard hex keys and socket drives

Compatibility

Designed for use in standard 7/8-9 UNC tapped holes or with matching UNC hex nuts in industrial and mechanical fastening applications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 3/4-inch hex key or socket driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Do not cross-thread; hand-start the screw before applying torque. When installing in stainless steel assemblies, apply an appropriate anti-seize compound to the threads to prevent galling.
