Value Collection 581163PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 581163PR is a hex socket cap screw designed for applications requiring a compact, high-strength threaded fastener in tight clearance areas. Threaded 5-40 UNC and fully threaded along its 1/8 inch length under head, this screw accepts a 3/32 inch hex drive. The alloy steel construction with a black oxide finish provides corrosion resistance and reduces light reflection in precision assemblies. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical and structural applications. Installers and maintenance technicians in manufacturing, instrumentation, and light mechanical assembly will find this fastener appropriate for small-clearance fastening tasks.

This screw is used in light industrial, precision instrument, electronics enclosure, and mechanical assembly applications where a low-profile socket head and fine 5-40 UNC threading are required. The fully threaded design maximizes thread engagement over the full grip length, which is useful in thin-material and close-tolerance assemblies. The black oxide coating suits indoor applications where mild corrosion resistance is acceptable. This fastener is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• 5-40 UNC thread size for fine-pitch engagement in small-diameter fastening applications
• Fully threaded along the entire 1/8 inch length under head
• 3/32 inch hex socket drive for use with standard Allen wrenches or hex keys
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides mild corrosion resistance and low-glare surface
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for precision mechanical assemblies, instrumentation housings, and light industrial equipment requiring 5-40 UNC socket cap screws.

Installation Notes

Installation should be performed by a qualified mechanic or assembly technician using a calibrated 3/32 inch hex key or T-handle driver. Ensure mating threads are clean and free of debris before driving. Do not exceed the rated torque range for the alloy steel material grade and thread size. Use thread-locking compound only if specified by the equipment manufacturer.
