Value Collection 211004PR Flat Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 211004PR is a flat socket cap screw designed for precision fastening applications requiring a flush or countersunk head profile. Sized at 0-80 UNF thread with an overall length of 3/8 inches, this screw is fully threaded and manufactured from alloy steel with a black oxide finish. The internal hex socket drive allows for high torque input in tight clearance areas. It meets ASME/ANSI B18.3 and ASTM F835 fastener standards, making it suitable for applications where dimensional and mechanical compliance is required. Installers in mechanical assembly, instrumentation, electronics, and light fabrication work regularly specify this type of fastener.

This flat socket cap screw is used where a low-profile or flush-mount fastening point is needed and space is limited. The 0-80 thread designation is among the smallest unified thread sizes, making this screw common in precision instruments, optical equipment, small mechanical assemblies, and electronic enclosures. The black oxide finish provides mild corrosion resistance suitable for indoor or controlled-environment use. This item is sold individually but has a minimum order quantity of 100 units, making it appropriate for shop stock or production-volume purchasing.

Key Features

• Flat head profile allows flush or countersunk installation in precision assemblies
• Hex socket drive enables high-torque input in confined spaces using standard hex keys
• Fully threaded along the entire 3/8-inch overall length for maximum thread engagement
• Alloy steel construction provides strength appropriate for small-diameter precision fasteners
• Black oxide finish offers mild corrosion resistance for controlled-environment applications
• Meets ASME/ANSI B18.3 and ASTM F835 standards for dimensional and mechanical compliance

Compatibility

Designed as an OEM-style or production replacement flat socket cap screw for precision assemblies using 0-80 UNF threaded fastener specifications per ASME/ANSI B18.3 and ASTM F835.

Installation Notes

Installation requires a properly sized hex key or hex bit driver matched to the socket drive. The mating hole should be tapped to 0-80 UNF specification and countersunk to accommodate the flat head geometry. Power down or de-energize any equipment before servicing assemblies that incorporate these fasteners. Avoid over-torquing small-diameter alloy steel screws, as the 0-80 thread size has limited torque capacity relative to larger fastener classes.
