Value Collection -36870-4 Flat Socket Cap Screw 3/4-10

Product Description

The VALUE COLLECTION -36870-4 is a flat socket cap screw designed for use in flush or countersunk fastening applications where a low-profile head is required. The 82-degree flat head seats fully into a countersunk hole, eliminating protrusion above the mating surface. Driven by a 1/2-inch hex socket, the fastener is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection. At 3/4-10 UNC thread and 2.5 inches in overall length, this screw is sized for medium-to-heavy structural and mechanical assemblies. Sold in packs of 10, it meets ASME/ANSI B18.3 and ASTM F835 standards.

This flat socket cap screw is suited for industrial machinery, tooling fixtures, structural steel fabrication, and general mechanical assembly where a flush-mount fastener is required. Fully threaded along its entire 2.5-inch length, it provides maximum thread engagement across a range of material thicknesses. The black oxide finish makes it a common choice in applications where surface glare or corrosion from mild environments is a concern. Machinists, millwrights, and maintenance technicians are the primary installers in both production and field-service settings.

Key Features

• 82-degree flat head for flush countersunk seating with no surface protrusion
• 1/2-inch hex socket drive for high-torque installation with standard Allen or hex key tooling
• 3/4-10 UNC fully threaded at 2.5 inches overall length for maximum thread engagement
• Alloy steel construction for high tensile and shear strength in structural applications
• Black oxide finish for mild corrosion resistance and low-reflectance surface
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards
• Sold in a pack of 10 with a minimum order quantity of 1 pack

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any countersunk application requiring a 3/4-10 UNC thread pattern and conforming to ASME/ANSI B18.3 dimensional standards.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or Allen driver. The mating countersink must be machined to an 82-degree included angle to achieve proper head seating. Ensure the receiving material is de-energized and secured before fastening in any mechanical assembly. Do not exceed the torque capacity of the alloy steel grade being used; consult the applicable fastener torque specification chart for 3/4-10 socket screws.
