Brighton-best 201099 Button Socket Cap Screw 1/4-20 X 3/4 in 100pk

Product Description

The BRIGHTON-BEST 201099 is a 1/4-20 x 3/4 inch button socket cap screw manufactured from steel alloy with a thermal black oxide finish. The low-profile domed head accepts a hex key drive, making it well suited for assemblies where clearance is limited or a flush, finished appearance is required. The full-thread (FT) UNC configuration provides consistent engagement across the entire shank length. This package contains 100 screws, making it practical for production runs, panel fabrication, and equipment assembly work where consistent fastener stock is needed.

Button socket cap screws in this size are commonly used in light machinery, electrical enclosures, HVAC equipment panels, brackets, and general mechanical assemblies. The 1/4-20 UNC thread is one of the most widely used coarse-thread sizes in North American trade applications. The thermal black oxide finish provides a moderate layer of corrosion resistance and reduces light reflection in finished assemblies. Licensed trades and fabricators working on metal panels and structural brackets will find this fastener suitable for indoor and protected-environment applications.

Key Features

• 1/4-20 UNC coarse thread, full thread length for maximum engagement
• 3/4 inch length suits medium-depth fastening in panels and brackets
• Steel alloy construction for reliable tensile and shear strength
• Thermal black oxide finish for corrosion resistance and low-glare appearance
• Low-profile button head design for use in clearance-restricted spaces
• Pack of 100 for production and service stock efficiency

Compatibility

Designed as a standard 1/4-20 UNC full-thread button socket cap screw suitable for use in any application requiring this thread size and a low-profile hex-drive fastener.

Installation Notes

Install using the appropriate hex key or Allen driver sized for the button head socket. Ensure mating threads are clean and free of debris before driving. Apply fastener torque appropriate for the assembly material and grade requirements per applicable mechanical standards. Thermal black oxide finish is best suited for dry or low-moisture indoor environments; additional corrosion protection may be needed in exposed or high-humidity installations.
