Value Collection 581002PR Hex Socket Cap Screw 0-80 Unf

Product Description

The VALUE COLLECTION 581002PR is a 0-80 UNF hex socket cap screw designed for precision fastening in tight-tolerance applications. Manufactured from alloy steel with a black oxide finish, this screw measures 5/16 inches under the head and is fully threaded from tip to head. The hex drive socket accepts a small hex key for controlled torque application in confined spaces. Black oxide coating provides moderate corrosion resistance and reduces light reflection in optical or instrument assemblies. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional and mechanical property compliance. Machinists, instrument technicians, and precision assembly workers are the primary installers of this fastener class.

The 581002PR is suited for small-scale mechanical assemblies, instrument housings, electronics enclosures, optical equipment, and precision machine components where a 0-80 UNF thread form is specified. The fully threaded design maximizes thread engagement in thin material applications. The black oxide finish is appropriate for interior or low-moisture environments. This screw is sold individually per package with a minimum order quantity of 100 pieces, making it practical for production assembly and maintenance inventory replenishment.

Key Features

• 0-80 UNF thread form for fine-pitch precision fastening
• Fully threaded body maximizes engagement in thin or shallow tapped holes
• Alloy steel construction for strength in small-diameter fastener applications
• Black oxide finish for moderate corrosion resistance and low reflectivity
• Hex socket drive for torque control in confined or recessed locations
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed for use in any application requiring a 0-80 UNF internally threaded hole with an ASME/ANSI B18.3 hex socket cap screw. Typical fitment includes precision instruments, optical assemblies, and small mechanical devices with fine-thread tapped bores.

Installation Notes

Installation requires a correctly sized hex key or hex bit driver matched to the 0.05-inch drive socket. Verify that the mating tapped hole is clean, properly formed to 0-80 UNF specification, and free of debris before driving the screw. Do not exceed the torque capacity of the 0-80 thread form, as small-diameter fasteners are susceptible to thread stripping and shank breakage under excessive load. Black oxide finish provides limited corrosion protection and is not a substitute for plated or stainless finishes in wet or outdoor environments.
