Value Collection 201004PR Button Socket Cap Screw 0-80

Product Description

The VALUE COLLECTION 201004PR is a button socket cap screw designed for precision fastening applications requiring a low-profile head and a hex socket drive. Manufactured from alloy steel with a black oxide coating, this screw measures 0-80 thread size with a 3/8-inch length under the head. It is fully threaded and conforms to ANSI/ASME B18.3 and ASTM F835 standards. The 3A thread fit class and UNF thread form ensure tight, consistent engagement in tapped holes. Hardness is rated at 36-43 HRC, making it suitable for applications that demand high tensile strength in a compact fastener profile. Licensed tradespeople and precision assembly technicians are the primary installers.

This screw is used in mechanical assemblies, tooling fixtures, machine components, and light structural applications where a flush or recessed fastener head is required. The button head profile reduces the risk of snagging in tight clearance environments. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity, making it a common choice in instrumentation, electronics enclosures, and industrial machinery. Sold in a package quantity of one with a minimum order quantity of 100 units.

Key Features

• Button head with hex socket drive for low-profile, recessed installation
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide coating for mild corrosion resistance and reduced reflectivity
• Fully threaded 0-80 UNF right-hand thread with 3A fit class
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards
• Head height of 0.032 inches for minimal stack height in tight assemblies

Compatibility

Designed as an OEM-style replacement or standard-fit fastener for assemblies requiring a 0-80 UNF button socket cap screw per ANSI/ASME B18.3 specifications.

Installation Notes

Installation is performed using a hex socket driver or Allen key sized for the 0-80 drive. Power down or de-energize any equipment before servicing fasteners in electrical or instrumentation enclosures. Use a thread gauge to verify tapped hole condition and thread class compatibility before installation. Avoid over-torquing — the small diameter and fine thread pitch make this screw sensitive to thread stripping if excessive force is applied.
