Value Collection R88444382 Machine Screw 3/8-16 X 1-1/2 Ss

Product Description

The VALUE COLLECTION R88444382 is a button head machine screw in 3/8-16 UNC thread with a 1-1/2 inch length measured under the head. It is manufactured from 18-8 stainless steel with a bright, uncoated finish, making it suitable for applications where corrosion resistance and a low-profile head are required. The pin-in hex socket drive adds tamper resistance compared to a standard hex socket. This fastener is sold in a minimum order quantity of 5 pieces and is intended for use by maintenance technicians, HVAC installers, electricians, plumbers, and other tradespeople who need a reliable, corrosion-resistant threaded fastener.

This screw is used in a wide range of trade and industrial applications where a button head profile is needed to keep the fastener head close to the mating surface. Common install scenarios include equipment panels, enclosures, brackets, and structural assemblies that call for a 3/8-16 UNC thread in inch-measurement systems. The uncoated stainless finish is well suited for both indoor and outdoor environments where moisture or chemical exposure may be a concern.

Key Features

• 3/8-16 UNC thread for compatibility with standard inch-system tapped holes
• 1-1/2 inch length measured under the head for accurate stack-up calculations
• Button head profile provides a low-profile, rounded appearance and broad bearing surface
• Pin-in hex socket drive adds tamper resistance over standard hex socket configurations
• 18-8 stainless steel construction offers corrosion resistance without a coating
• Bright, uncoated finish — no plating buildup to affect thread fit

Compatibility

Designed for use in any application requiring a 3/8-16 UNC inch-thread button head machine screw with a pin-in hex socket drive and 18-8 stainless steel material.

Installation Notes

Installation requires a pin-in hex socket driver sized for 3/8-inch button head fasteners — a standard hex key will not engage the center pin and should not be substituted. Apply appropriate thread lubricant or anti-seize compound when torquing stainless fasteners into stainless tapped holes to prevent galling. Always verify thread engagement depth meets the requirements of the assembly before final torque. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener selection and installation.
