Value Collection -40865-3 Button Socket Cap Screw 10-32 100pk

Product Description

The VALUE COLLECTION -40865-3 is a button head socket cap screw designed for precision fastening applications requiring a low-profile head and high clamping strength. Sized at 10-32 UNF with a 7/16-inch length under head, this screw is fully threaded and manufactured from alloy steel with a black oxide finish. The hex socket drive accepts a 1/8-inch hex key. Black oxide provides moderate corrosion resistance and reduces light reflection in finished assemblies. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards and is suited for mechanical assembly, machine building, and equipment maintenance work performed by machinists, millwrights, and maintenance technicians.

This screw is appropriate for use in light-duty to medium-duty mechanical assemblies where a low-profile button head is required to clear adjacent components or provide a flush appearance. The 10-32 UNF thread is common in precision instruments, electronics enclosures, and general industrial equipment. The black oxide finish makes it suitable for indoor applications where mild corrosion resistance is acceptable. Sold in a package of 100 pieces, this fastener is well suited for shop stock, field service kits, or MRO replenishment.

Key Features

• 10-32 UNF fully threaded, right-hand thread with Thread Fit Class 3A for close-tolerance fits
• 7/16-inch length under head for shallow to mid-depth through-hole applications
• Button head profile reduces protrusion in assemblies with clearance constraints
• Alloy steel construction with hardness rated at 36-43 HRC for high tensile strength
• Black oxide finish reduces glare and provides light rust inhibition in dry environments
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or stock fastener for any application calling for a 10-32 UNF button socket cap screw with a 7/16-inch length under head, 1/8-inch hex socket drive, and black oxide alloy steel construction per ANSI/ASME B18.3 and ASTM F835.

Installation Notes

Installation is typically performed by machinists, assembly technicians, or maintenance personnel using a 1/8-inch hex key or socket driver. Ensure mating threads are clean and free of debris before driving. Do not exceed the design torque rating for the thread size and material combination - refer to applicable engineering references for 10-32 alloy steel fastener torque values. Inspect for thread damage before reuse in critical assemblies.
