Value Collection 4.1421BS 1/4-20 X 1 in Button Head Torx Screw

Product Description

The VALUE COLLECTION 4.1421BS is a 1/4-20 button head machine screw designed for general fastening applications where a low-profile, smooth head profile is required. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw offers solid corrosion resistance suitable for interior and moderate exterior environments. The Torx drive reduces cam-out during installation and allows higher torque transfer compared to Phillips or slotted drives. Thread form is UNC (Unified National Coarse), and the 1-inch length is measured under the head. This fastener is installed by maintenance technicians, electricians, HVAC mechanics, and general tradespeople working with panel assemblies, equipment enclosures, and structural brackets.

This screw is suited for light to medium-duty fastening tasks in residential and commercial applications. Common uses include securing electrical enclosure panels, HVAC component brackets, control board mounting, and equipment housing assemblies. The button head profile sits close to the mating surface, making it a practical choice in tight clearance installations where a standard hex or pan head would interfere with adjacent components. The 1/4-20 UNC thread engages standard tapped holes and threaded inserts found across a wide range of equipment and structural members.

Key Features

• 1/4-20 UNC thread for compatibility with standard tapped holes and threaded inserts
• Button head profile provides low-profile seating in clearance-sensitive assemblies
• Torx drive reduces cam-out and supports higher installation torque
• 18-8 stainless steel construction resists corrosion in moderate environments
• Bright, uncoated finish — no plating to chip, flake, or contaminate contact surfaces
• 1-inch length measured under head for consistent, predictable thread engagement depth

Compatibility

Designed as a standard 1/4-20 UNC machine screw for use in equipment panels, enclosures, and mechanical assemblies that accept 1/4-20 tapped holes or threaded inserts requiring a button head, Torx-drive fastener.

Installation Notes

Installation requires a Torx driver or bit of the appropriate size for the 1/4-20 button head screw. Always verify the mating thread is clean and in good condition before driving the fastener. De-energize electrical panels and equipment per NFPA 70 (NEC) lockout/tagout procedures before accessing internal mounting hardware. Avoid over-torquing stainless steel fasteners, as 18-8 alloys are susceptible to galling — use a calibrated torque tool and apply an appropriate anti-seize compound when required by the application.
