Value Collection R88448038 1/4-20 X 1-1/2 Button Head Screw

Product Description

The VALUE COLLECTION R88448038 is a 1/4-20 x 1-1/2 inch button head machine screw manufactured from 18-8 stainless steel with a bright, uncoated finish. The button head profile sits low against mating surfaces, making it a practical choice where a flush or low-profile fastener is required. The Pin-In Torx drive adds tamper resistance, limiting removal to authorized technicians with the appropriate driver bit. Thread standard is UNC (Unified National Coarse) at 1/4-20, measured from under the head. This screw is appropriate for use in HVAC equipment panels, electrical enclosures, plumbing fixtures, and general mechanical assemblies where corrosion resistance is a priority.

This fastener suits residential and light commercial applications that require a corrosion-resistant, tamper-resistant fastening solution. Typical installation scenarios include securing control panels, equipment covers, and structural components in environments exposed to moisture or chemical contact. The 18-8 stainless steel construction resists rust and oxidation, making it appropriate for both indoor and outdoor mechanical assemblies. This item is sold with a minimum order quantity of 25 units per order.

Key Features

Compatibility

Designed as a standard UNC 1/4-20 x 1-1/2 inch button head machine screw suitable for use in any application accepting this thread size and head style.

Installation Notes

Install using a Pin-In Torx driver bit of the appropriate size — a standard Torx bit will not properly engage the pin-in socket. Power down or de-energize any equipment before accessing fastener locations inside electrical or HVAC enclosures. Follow applicable NEC or equipment manufacturer guidelines when reinstalling access panels or control covers. Do not overtighten into tapped holes in soft base materials, as stainless steel fasteners can gall if driven without appropriate lubrication or controlled torque.
