Value Collection 592469BR Hex Socket Cap Screw 7/8-9 Unc

Product Description

The VALUE COLLECTION 592469BR is a hex socket cap screw designed for high-strength fastening applications requiring corrosion resistance and precise thread engagement. It features a 7/8-9 UNC thread form and a 2-inch length under head, with full threading along the entire shank. The 3/4-inch hex drive accepts standard hex keys and Allen-style socket tools. Constructed from 18-8 austenitic stainless steel (Grade A2), this fastener resists rust and chemical exposure without a surface coating, making it suitable for both interior and exterior assemblies. Plumbers, HVAC technicians, electricians, and mechanical contractors install fasteners of this type when corrosion resistance is a priority over raw tensile strength.

This screw is appropriate for general mechanical assemblies, equipment mounting, pipe support hardware, panel attachment, and structural bracketing in environments where mild corrosive exposure is present. The fully threaded shank provides maximum thread engagement across the full grip length, which is advantageous in thinner material stacks or when thread depth is limited. It is sold individually and suits both shop fabrication and field service applications across residential and light commercial trades.

Key Features

• 7/8-9 UNC thread for broad tool and hardware compatibility
• 2 inches length under head, fully threaded shank
• 3/4-inch hex socket drive for use with standard hex keys or socket drivers
• 18-8 austenitic stainless steel, Grade A2, for corrosion resistance
• Bright uncoated finish suitable where coatings could interfere with tolerances
• Meets ASME/ANSI B18.3 and ASTM F837 fastener standards

Compatibility

Designed as a standard-dimension hex socket cap screw per ASME/ANSI B18.3 and ASTM F837, suitable for use in any application accepting a 7/8-9 UNC fully threaded socket cap screw with a 2-inch length under head.

Installation Notes

Installation is performed using a 3/4-inch hex key or socket driver. Verify that the mating threaded hole or nut is also rated for 7/8-9 UNC before installation. De-energize or depressurize any system before fastener replacement or tightening in live mechanical or electrical assemblies. Avoid mixing stainless steel fasteners with dissimilar metals in submerged environments without accounting for galvanic compatibility.
