Value Collection R88444342 Button Head Screw 1/4-20 X 3/4

Product Description

The VALUE COLLECTION R88444342 is a 1/4-20 x 3/4 inch button head machine screw designed for mechanical assembly applications requiring a low-profile fastener head. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw offers good corrosion resistance suitable for general-purpose industrial and light commercial use. The pin-in hex socket drive adds a tamper-resistant element, making it appropriate for panels, enclosures, and equipment covers where unauthorized removal is a concern. Thread standard is Unified National Coarse (UNC), and length is measured under the head. Licensed tradespeople and maintenance technicians working with mechanical assemblies will encounter this fastener type frequently.

This screw is suited for light-gauge metal and plastic panel assembly, HVAC equipment enclosures, electrical control boxes, and general machinery fabrication. The button head profile sits flush and low against mating surfaces, reducing snag hazards in tight spaces. The 1/4-20 UNC thread is a widely used coarse-thread standard, making this fastener compatible with a broad range of tapped holes and threaded inserts found in trade equipment and assemblies. Minimum order quantity is 100 pieces per order.

Key Features

• Button head profile for low-profile, snag-resistant installations
• Pin-in hex socket drive provides tamper resistance on panels and enclosures
• 18-8 stainless steel construction offers corrosion resistance for indoor and mild-exposure applications
• Bright, uncoated finish maintains dimensional consistency and conductivity where needed
• 1/4-20 UNC thread is a standard coarse pitch compatible with common tapped holes and inserts
• Length measured under head at 3/4 inch, ensuring accurate fitment calculations

Compatibility

Designed as a standard 1/4-20 UNC button head replacement fastener suitable for any tapped hole or threaded insert conforming to 1/4-20 UNC thread specifications in mechanical assemblies, equipment enclosures, and control panels.

Installation Notes

Installation requires a pin-in hex socket driver or bit sized for 1/4-20 button head fasteners. Always ensure the mating tapped hole or threaded insert is clean and free of debris before driving. Do not overtighten, as button head fasteners have lower drive-out torque thresholds than hex cap or socket head cap screws. Follow applicable mechanical and electrical codes when using fasteners in code-governed assemblies.
