Value Collection -40868-7 Button Cap Screw 10-32 50-pack

Product Description

The VALUE COLLECTION -40868-7 is a 10-32 button socket cap screw designed for precision fastening applications requiring a low-profile head and high tensile strength. Manufactured from alloy steel with a black oxide finish, this fully threaded fastener measures 1.5 inches in length under the head and features a hex socket drive sized at 1/8 inch. With a hardness rating of 36-43 HRC and a 3A thread fit class, this screw is suited for machine assembly, equipment fabrication, and close-tolerance mechanical work. It conforms to ANSI/ASME B18.3 and ASTM F835 standards. This package contains 50 screws.

The -40868-7 button socket cap screw is used in light to medium-duty mechanical assemblies where a flush or near-flush fastener profile is required. The button head style distributes clamping load over a wider bearing surface than a standard cap screw, making it appropriate for thin sheet metal work, panel mounting, jig and fixture assembly, and general machine building. The UNF thread standard suits applications demanding finer thread engagement and superior vibration resistance compared to UNC equivalents.

Key Features

• 10-32 UNF fully threaded, right-hand thread with 3A thread fit class for close-tolerance assemblies
• Alloy steel construction with 36-43 HRC hardness for high shear and tensile strength
• Black oxide finish provides moderate corrosion resistance and reduces light glare on exposed fasteners
• Low-profile button head at 0.101 inches head height minimizes protrusion in confined installations
• 1/8-inch hex socket drive compatible with standard hex keys and socket bits
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 10-32 UNF button socket cap screw for use in any mechanical assembly requiring an ANSI/ASME B18.3 or ASTM F835 compliant fastener with a button head profile.

Installation Notes

Installation is performed using a 1/8-inch hex key or Allen-head bit driver. Ensure mating threads are clean and free of debris before driving to avoid cross-threading. Do not exceed the recommended seating torque for alloy steel 10-32 fasteners as specified in your assembly documentation. Apply thread-locking compound only if specified by the equipment manufacturer.
