Value Collection 592179PR Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION 592179PR is a partially threaded hex socket cap screw designed for precision fastening in mechanical, industrial, and structural assemblies. Sized at 8-32 UNC thread with a 2.5-inch length under the head, this fastener accepts a 9/64-inch hex drive for installation with a standard Allen wrench or hex key. Constructed from 18-8 austenitic stainless steel (Material Grade A2), it provides solid corrosion resistance for both indoor and outdoor applications. It meets ASME/ANSI B18.3 and ASTM F837 standards, making it suitable for use in environments where dimensional and material compliance is required.

This screw is appropriate for general mechanical assembly, machine component mounting, and fabrication work where a recessed drive and flush or countersunk head profile are needed. The partial threading allows the shank to bear shear loads while the threaded section engages a tapped hole or nut. Typical applications include equipment enclosures, machine frames, and light structural connections across residential and commercial trade environments. Installation is performed by licensed or journeyman-level tradespeople and experienced fabricators working with standard hand tools.

Key Features

• 8-32 UNC thread for compatibility with standard tapped holes and nuts in that size class
• 2.5-inch length under head provides sufficient grip range for thicker assemblies
• Partially threaded shank handles shear loads independently of the threaded section
• 18-8 austenitic stainless steel (Grade A2) resists rust and corrosion in wet or humid conditions
• 9/64-inch hex socket drive works with standard Allen wrenches and hex-key drivers
• Meets ASME/ANSI B18.3 and ASTM F837 standards for dimensional and material conformance

Compatibility

Designed as a standard 8-32 UNC hex socket cap screw suitable for tapped holes or mating nuts conforming to ASME/ANSI B18.3 specifications in mechanical and industrial assemblies.

Installation Notes

Install using a calibrated hex key or Allen driver of the correct 9/64-inch size to avoid rounding the socket. Ensure the receiving hole is clean, properly tapped to 8-32 UNC, and free of debris before driving the fastener. Apply appropriate thread engagement depth per the applicable ASME standard for the material being fastened. Do not over-torque stainless steel fasteners, as galling can occur without proper lubrication.
