Value Collection 36818 Flat Socket Cap Screw 1/4-20 X 2 in

Product Description

The VALUE COLLECTION 36818 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. With a 1/4-20 UNC thread and an overall length of 2 inches, this screw is partially threaded and driven by a 5/32 inch hex socket. The 82-degree flat head seats flush with the mating surface when installed in a properly countersunk hole. Constructed from alloy steel with a black oxide finish, it offers solid mechanical strength and moderate corrosion resistance in dry or lightly oiled environments. Licensed tradespeople and maintenance technicians working on HVAC equipment enclosures, electrical panels, and general mechanical assemblies commonly specify this fastener type.

This fastener suits a wide range of trade and industrial applications where a low-profile, countersunk head is required. It is appropriate for light structural, mechanical, and enclosure assembly work in residential and commercial settings. The black oxide finish makes it a common choice in applications where a non-reflective or dark appearance is preferred alongside standard alloy steel strength. It meets ASME/ANSI B18.3 and ASTM F835 fastener standards, making it suitable for applications referencing those specifications.

Key Features

• 82-degree flat head seats flush in standard countersunk holes
• 5/32 inch hex socket drive for precise torque application with a standard Allen wrench or hex key bit
• Partially threaded shank allows clamping force between mating components
• Alloy steel construction provides high tensile strength relative to standard carbon steel fasteners
• Black oxide finish delivers a non-reflective appearance and light corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM F835 standards

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application specifying a 1/4-20 UNC partially threaded flat head socket screw per ASME/ANSI B18.3 or ASTM F835.

Installation Notes

Installation requires a properly sized countersunk hole to allow the 82-degree flat head to seat flush with the workpiece surface. Use a calibrated 5/32 inch hex key or driver bit and follow applicable torque guidelines for 1/4-20 alloy steel fasteners per the relevant mechanical or equipment specification. De-energize and lock out any electrical or mechanical equipment before fastener service where required by OSHA or applicable codes. Avoid over-torquing, which can strip threads or crack the countersink in softer base materials.
