Value Collection 701165PR Button Socket Cap Screw 5/16-24x2

Product Description

The VALUE COLLECTION 701165PR is a button socket cap screw designed for applications requiring a low-profile fastener with high tensile strength. Sized at 5/16-24 (UNF) with a 2-inch length under the head, it features a 3/16-inch hex socket drive and a fully threaded shank. Constructed from alloy steel with a black oxide coating, this screw meets ANSI/ASME B18.3 and ASTM F835 standards. Hardness is rated at 36-43 HRC, making it appropriate for demanding mechanical assemblies. Machinists, millwrights, and maintenance technicians are the typical installers.

This button socket cap screw is suited for use in mechanical assemblies, fixtures, machine frames, and enclosures where a low-profile head is required to clear adjacent components or mating surfaces. The UNF thread form is standard in precision and aerospace-adjacent applications. The black oxide finish provides mild corrosion resistance and reduces light reflection in visible assemblies. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Low-profile button head allows clearance in tight or recessed installations
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide coating for mild corrosion resistance and a matte appearance
• 3/16-inch hex socket drive for use with standard Allen or hex key tools
• Fully threaded shank with 5/16-24 UNF right-hand thread, Class 3A fit
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-dimension UNF button socket cap screw per ANSI/ASME B18.3 and ASTM F835, suitable for tapped holes accepting a 5/16-24 thread in any compatible mechanical assembly.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver. Ensure the mating tapped hole is clean and properly formed to Class 3A thread tolerances before installation. Do not exceed the torque rating specified for the assembly material and joint design. Proper thread engagement depth should be confirmed before applying final load.
