Value Collection 581492PS Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 581492PS is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment maintenance. Manufactured from alloy steel with a black oxide finish, this fastener provides a combination of tensile strength and moderate corrosion resistance. The 3/8-24 UNF thread is a fine-pitch profile suited for applications requiring precise clamping force or vibration resistance. Drive is 5/16 inch hex socket, compatible with standard Allen keys and hex socket drivers. The 1-1/8 inch length under head and fully threaded shank make it appropriate for through-hole and close-tolerance fastening work. Installed by maintenance technicians, millwrights, and general tradespeople.

This screw is suited for use in ferrous and non-ferrous assemblies where a recessed socket drive is preferred over external hex or slotted heads. The fully threaded body allows engagement across the entire shank length, making it appropriate for thin-material or short-grip applications. The black oxide finish reduces galling during installation and provides light surface protection in dry or low-moisture environments. Typical applications include machine frames, brackets, enclosures, and mechanical component mounting in industrial and HVAC equipment contexts.

Key Features

• 3/8-24 UNF fine-pitch thread for high clamping force and vibration resistance
• Fully threaded shank for maximum thread engagement across the full grip length
• 5/16 inch hex socket drive compatible with standard Allen keys and socket drivers
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish reduces surface friction and offers light corrosion protection
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and strength standards

Compatibility

Designed as a standard 3/8-24 UNF hex socket cap screw per ASME/ANSI B18.3, suitable for use in any assembly specifying this thread size, drive type, and length under head.

Installation Notes

Install with a calibrated hex key or socket driver sized to the 5/16 inch drive to avoid rounding the socket recess. Verify thread engagement and hole depth before final torque to prevent bottoming out. Black oxide fasteners are not intended for prolonged exposure to moisture, chemicals, or outdoor environments without additional protection. Follow equipment manufacturer torque specifications and applicable mechanical codes for the assembly being serviced.
