Value Collection 581230PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 581230PR is a hex socket cap screw designed for precision fastening in mechanical and structural assemblies. Threaded 6-40 UNF and measuring 7/16 inches under the head, this screw is fully threaded along its entire length, allowing consistent clamp load from head to tip. It is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a low-reflectance appearance. The 7/64-inch internal hex drive accepts a standard hex key or Allen wrench. This fastener meets ASME/ANSI B18.3 and ASTM A574 specifications. It is suitable for use in equipment assembly, tooling, fixture work, and precision mechanical installations across industrial and trade applications.

The 581230PR is appropriate for applications requiring a fine-thread socket cap screw in a compact size. The 6-40 UNF thread pitch provides greater thread engagement per unit length compared to coarse-thread alternatives, making it a preferred choice in thin materials, aluminum components, or anywhere vibration resistance is a priority. Typical install scenarios include machine tool assemblies, small equipment enclosures, and precision fixtures where a low-profile, high-strength socket head is needed.

Key Features

• 6-40 UNF fine thread for superior vibration resistance and holding strength in thin or soft materials
• Fully threaded shank for maximum thread engagement along the entire fastener length
• Alloy steel construction meets ASTM A574 high-strength socket cap screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 7/64-inch hex drive compatible with standard hex keys and Allen wrenches
• Conforms to ASME/ANSI B18.3 dimensional standards for socket head cap screws

Compatibility

Designed as a standard 6-40 UNF hex socket cap screw conforming to ASME/ANSI B18.3 dimensional requirements, suitable for use in any application or assembly calling for this thread size and drive type.

Installation Notes

Installation is performed with a 7/64-inch hex key or Allen wrench. Ensure the mating threaded hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or thread-locking compound as required by the assembly specification. Avoid over-torquing, which can strip fine UNF threads in softer base materials.
