Value Collection 581056PR Hex Socket Cap Screw 2-64 Unf

Product Description

The VALUE COLLECTION 581056PR is a hex socket cap screw designed for precision fastening applications requiring a compact, high-strength threaded fastener. Built from alloy steel with a black oxide coating, this screw features a 2-64 UNF thread size and a 5/64-inch hex drive. The length under the head measures 1/8 inch. It is fully threaded along its entire shank. The black oxide finish provides a degree of corrosion resistance and surface hardness suited to close-tolerance mechanical assemblies. This fastener is manufactured to ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for engineers, machinists, and maintenance technicians working on precision equipment.

This screw is commonly used in tight-clearance assemblies where a low-profile socket drive is necessary. Typical applications include instrument panels, small machinery, electronic enclosures, and precision mechanical components where standard larger fasteners will not fit. The 2-64 UNF thread pitch is a fine thread commonly found in miniature and instrument-grade assemblies across industrial and commercial settings.

Key Features

• 2-64 UNF fully threaded shank for fine-thread precision engagement
• 5/64-inch hex socket drive for use with standard Allen or hex key tools
• 1/8-inch length under head for low-profile, tight-clearance installations
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide coating provides surface protection and reduces light reflection
• Manufactured to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in precision mechanical assemblies, instrumentation, and close-tolerance fastening applications requiring 2-64 UNF thread engagement.

Installation Notes

Installation requires a 5/64-inch hex key or Allen driver; use a calibrated torque driver when assembling into tapped holes in soft materials to avoid thread stripping. Ensure mating tapped holes are clean and free of debris before driving. Machinists and maintenance technicians should verify thread fit with a GO/NO-GO gauge when working in precision or safety-critical assemblies. Minimum order quantity is 100 pieces per order.
