Value Collection 015285PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 015285PR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. It features a 3/8-24 UNF thread size — a fine-thread specification that delivers greater thread engagement and improved resistance to loosening under vibration. The screw is fully threaded with a 5/8 inch length under head and is driven by a 5/16 inch hex socket. Constructed from alloy steel with a black oxide finish, this fastener provides good corrosion resistance and is well suited for interior or protected environments. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in precision assemblies, brackets, and equipment housings.

This socket cap screw is used across a wide range of applications requiring fine-thread clamping force in a compact-head profile. The 3/8-24 UNF thread makes it a common choice in hydraulic fittings, pump housings, machine tool components, and automotive assemblies where vibration and load are factors. The low-profile socket head allows installation in counterbored holes where clearance is limited. This fastener is sold individually per package with a minimum order quantity of 10 units.

Key Features

• 3/8-24 UNF fine thread for high clamping force and vibration resistance
• Fully threaded shank provides maximum thread engagement throughout the grip length
• 5/8 inch length under head suits shallow counterbore and tight-clearance installations
• 5/16 inch hex socket drive compatible with standard hex key and socket drivers
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection

Compatibility

Designed as a standard ASME/ANSI B18.3 socket head cap screw, compatible with any tapped hole or nut conforming to 3/8-24 UNF thread standards.

Installation Notes

Install with a properly sized 5/16 inch hex key or socket driver to avoid rounding the drive recess. Ensure the mating tapped hole is clean and free of debris before threading to prevent galling the alloy steel threads. Apply thread-locking compound or hardened washers as required by the assembly specification to maintain clamp load in high-vibration environments. Follow applicable ASME or equipment manufacturer torque specifications for 3/8-24 UNF fasteners at the appropriate grade.
