Value Collection 581490PR Hex Socket Cap Screw 3/8-24 Unf

Product Description

The VALUE COLLECTION 581490PR is a hex socket cap screw designed for precision fastening in mechanical, industrial, and maintenance applications. Threaded 3/8-24 UNF with a 3/8 inch length under head and a 5/16 inch internal hex drive, this fastener is fully threaded from the bearing surface to the tip. Constructed from alloy steel with a black oxide coating, it delivers solid mechanical strength and baseline corrosion resistance in controlled environments. Licensed technicians and maintenance professionals use this type of fastener where a flush or low-profile head and high clamping force are required.

This screw is suited for equipment assembly, machinery repair, and general mechanical work where UNF fine-thread engagement is specified. The 3/8-24 UNF thread pitch offers tighter thread spacing than standard coarse-thread fasteners, making it appropriate for applications where vibration resistance or precise torque control is important. A 5/16 inch hex key or Allen driver is required for installation and removal. Minimum order quantity is 10 pieces.

Key Features

• 3/8-24 UNF fine thread for tighter engagement and vibration resistance
• Fully threaded from under-head to tip for maximum thread engagement in shorter stack-ups
• Alloy steel construction rated to ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 5/16 inch internal hex drive accepts standard hex keys and socket drivers

Compatibility

Designed as a standard UNF hex socket cap screw per ASME/ANSI B18.3 and ASTM A574 for use in any application requiring a 3/8-24 fine-thread socket head fastener.

Installation Notes

Installation is performed with a 5/16 inch hex key or Allen-style driver. Ensure mating threads are clean and free of debris before installation. Power down or de-energize any equipment before accessing fastened assemblies. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for this fastener size and grade.
