Value Collection 011049PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 011049PR is a hex socket cap screw designed for applications requiring a secure, low-profile fastener with a recessed drive. Sized at 5-40 UNC with a 5/8-inch length under head and a 3/32-inch hex drive, this screw is fully threaded along its entire shank. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. Machinists, millwrights, and maintenance technicians commonly use this fastener in precision assemblies, jigs, fixtures, and light mechanical equipment where socket access is needed.

This fastener is suited for general industrial and mechanical assembly work where a #5-40 UNC thread pattern is specified. The 5/8-inch under-head length accommodates a range of material stack thicknesses in sheet metal, machined components, and fabricated assemblies. The hex socket drive allows torque application with a standard hex key or Allen driver in confined spaces where a conventional external-drive fastener would not fit. Full threading maximizes thread engagement when fastening into tapped holes or threaded inserts.

Key Features

• 5-40 UNC thread form for compatibility with standard unified coarse-thread tapped holes
• Fully threaded shank maximizes thread engagement across the entire fastener length
• 3/32-inch hex socket drive accepts standard hex keys and Allen drivers
• Alloy steel construction provides high tensile strength for its size class
• Black oxide finish reduces surface reflectivity and offers light rust inhibition
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as an OEM-style replacement or standard-supply fastener for any application specifying a 5-40 UNC hex socket cap screw with a 5/8-inch length under head and 3/32-inch drive per ASME/ANSI B18.3.

Installation Notes

Installation is performed by machinists, assemblers, or maintenance technicians using a 3/32-inch hex key or ball-end Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated mechanical torque for a size 5 alloy steel cap screw as specified in relevant ASME or ASTM standards. Black oxide is a mild finish only — apply thread-locking compound or anti-corrosion treatment when the installation environment involves moisture or chemicals.
