Value Collection 15425BR Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 15425BR is a hex socket cap screw engineered for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 5/8-11 UNC with a 3-inch length under head, this screw is partially threaded and driven with a 1/2-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and reduced surface glare in demanding service environments. It conforms to ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for precision-tolerance fastening where material and dimensional specs are critical.

This cap screw is used across a wide range of trade and industrial applications including machinery assembly, structural brackets, equipment mounting, and maintenance repair operations. The partially threaded shank allows for precise clamping force without thread engagement through the full grip length, which is useful in bolted joint applications requiring a smooth shank bearing surface. Machinists, millwrights, and maintenance technicians commonly install this type of fastener in fabrication shops, manufacturing facilities, and field service situations.

Key Features

• 5/8-11 UNC thread size for broad compatibility with standard UNC tapped holes
• 3-inch length under head with partial threading for controlled clamping applications
• 1/2-inch hex drive for use with standard hex keys and socket drive tools
• Alloy steel construction for high tensile strength and durability
• Black oxide finish provides mild corrosion resistance and low-reflectance surface
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as a standard-specification hex socket cap screw for use in any application requiring a 5/8-11 UNC partially threaded fastener with a 3-inch length under head.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket drive tool. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or anti-seize compound per your application requirements. Always torque to the specification called out in the assembly drawing or equipment service manual for the given joint material and fastener grade.
