Holo-krome 73082 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The HOLO-KROME 73082 is a hex socket cap screw designed for high-strength fastening applications requiring a compact, recessed drive. It features a 5/16-24 UNF thread and measures 7/8 inches under the head. The fastener is fully threaded and driven with a 1/4 inch hex key. Constructed from alloy steel with a black oxide coating, it provides solid mechanical strength and moderate corrosion resistance in controlled environments. This screw is installed by mechanical, industrial, and HVAC-equipment technicians wherever a flush or low-profile hex socket fastener is specified.

This cap screw is suited for precision assemblies, machinery, brackets, and equipment panels that call for a fine-thread UNF fastener. Fine-thread UNF specifications offer stronger thread engagement per unit length compared to coarse-thread UNC, making this screw appropriate for applications involving vibration or where precise preload control matters. It conforms to ASME B18.3 and ASTM A574 standards, which are common requirements for industrial and mechanical equipment fasteners.

Key Features

• 5/16-24 UNF fine thread for high thread engagement and vibration resistance
• Fully threaded shank for maximum fastening flexibility
• 1/4 inch hex socket drive for standard hex key installation
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish for surface protection in dry or lightly oiled environments
• Meets ASME B18.3 dimensional standard

Compatibility

Designed as an OEM-style replacement or maintenance fastener for machinery, equipment assemblies, and structural components requiring a 5/16-24 UNF hex socket cap screw per ASME B18.3.

Installation Notes

Install with a calibrated 1/4 inch hex key or hex bit driver. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before replacing fasteners on live machinery per applicable safety procedures. Do not exceed the rated torque for the thread class and material as specified in the applicable engineering documentation.
