Value Collection R88444692 Button Head Screw 1/4-20 X 1

Product Description

The VALUE COLLECTION R88444692 is a 1/4-20 x 1 inch button head machine screw made from 18-8 stainless steel with a bright, uncoated finish. It features a pin-in hex socket drive and a UNC thread standard, making it a reliable fastener for general mechanical assembly. The button head profile provides a low-profile clamping surface suited for applications where clearance is limited. At 0.0012 pounds per fastener, it is a lightweight component typically installed by machinists, millwrights, or maintenance technicians working in light industrial, commercial, or trade service environments.

This screw is suited for use in general-purpose mechanical assemblies where a corrosion-resistant fastener with a low-profile head is required. The 18-8 stainless steel construction resists rust and oxidation in moderate environments, making it appropriate for both indoor and light outdoor service. Length is measured under the head. This SKU ships in a minimum order quantity of 100 pieces per order.

Key Features

• Button head profile provides low-profile seating with a broad bearing surface
• Pin-in hex socket drive adds tamper resistance compared to standard hex socket fasteners
• 18-8 stainless steel construction resists corrosion and oxidation
• Bright uncoated finish suitable for assemblies where coating buildup on threads must be avoided
• UNC thread standard ensures broad compatibility with standard 1/4-20 threaded inserts and nuts
• Inch measurement system with length measured under the head

Compatibility

Designed as an OEM-style replacement or general-purpose fastener for mechanical assemblies requiring a 1/4-20 UNC button head machine screw with a pin-in hex socket drive in 18-8 stainless steel.

Installation Notes

Installation is typically performed by a machinist, maintenance technician, or licensed trade professional using a pin-in hex socket driver of the correct size. Ensure the mating threaded hole or nut is clean and free of debris before driving the fastener. Do not overtighten, as button head fasteners have a lower torque capacity than standard hex or socket head cap screws of the same diameter. Stainless steel fasteners are susceptible to galling; apply an appropriate anti-seize compound when torque retention is critical.
