Value Collection R88444981 1/4-20 X 1 Button Head Screw

Product Description

The VALUE COLLECTION R88444981 is a 1/4-20 x 1 inch button head machine screw designed for general fastening applications in industrial, mechanical, and structural assemblies. Machined from 18-8 stainless steel with a bright uncoated finish, it resists corrosion without the added thickness of a plated coating. The button head profile provides a low-profile bearing surface, while the Pin-In Torx drive requires a matching security bit, making it a common choice where tamper resistance is a consideration. Length is measured under the head. Thread standard is Unified National Coarse (UNC).

This screw is suited for light to medium-duty fastening in fabricated assemblies, enclosures, HVAC equipment panels, electrical boxes, and similar applications where stainless steel corrosion resistance is required. The 1/4-20 UNC thread pattern is widely used across commercial and industrial equipment. Installation is typically performed by mechanical contractors, equipment assemblers, maintenance technicians, or electricians working on panel and enclosure builds.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet or outdoor-adjacent environments
• Button head profile offers low-profile clamping with a wide bearing surface
• Pin-In Torx drive provides tamper-resistant fastening compared to standard Torx or Phillips drives
• Bright uncoated finish maintains precise thread tolerances without coating buildup
• 1/4-20 UNC thread is a standard, widely available fastener size
• Length measured under head for accurate stack-up and clearance calculations

Compatibility

Designed as a standard 1/4-20 UNC machine screw suitable for use in any application requiring a button head, Pin-In Torx drive fastener in 18-8 stainless steel.

Installation Notes

Installation requires a Pin-In Torx security bit matched to the drive size. Ensure the mating thread is tapped or threaded to 1/4-20 UNC specification before installation. Stainless steel fasteners can be prone to galling under high-speed installation; apply appropriate anti-seize compound and use low torque settings or hand-drive when threading into stainless mating parts. Power down or de-energize any equipment before fastening work on live assemblies.
