Value Collection R88444330 Machine Screw 3/8-16 X 1

Product Description

The VALUE COLLECTION R88444330 is a 3/8-16 x 1 inch button head machine screw built for industrial and trade applications where corrosion resistance and reliable fastening are required. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this fastener features a pin-in hex socket drive and a low-profile button head. The 3/8-16 thread designation follows Unified National Coarse (UNC) standards, and length is measured under the head. This screw is sold in a minimum order quantity of 5 pieces and is suited for installation by maintenance technicians, millwrights, and general contractors working with stainless hardware.

This fastener is appropriate for use in residential and commercial mechanical assemblies, equipment panels, brackets, and structural connections where a flush or low-profile head is preferred. The button head profile distributes load across a wider bearing surface compared to a flat or pan head, making it a practical choice in sheet metal, plastic, or light structural installations. The pin-in hex socket drive deters tampering, making it common in access panels, enclosures, and equipment covers in HVAC, plumbing, and electrical service environments.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Button head profile provides a low-profile, wide-bearing seating surface
• Pin-in hex socket drive offers tamper resistance for secured enclosures and panels
• 3/8-16 UNC thread standard ensures broad compatibility with standard tapped holes and hex nuts
• Bright, uncoated finish maintains dimensional accuracy and avoids coating-related tolerance concerns
• Length measured under head for precise installation depth planning

Compatibility

Designed as a standard 3/8-16 UNC machine screw suitable for use with any tapped hole or nut conforming to Unified National Coarse thread specifications in inch-measurement systems.

Installation Notes

Installation requires a pin-in hex socket bit of the appropriate size to engage the drive recess. Ensure the mating hole or nut is tapped to 3/8-16 UNC specification before installation. When fastening into stainless steel threads, apply an anti-seize compound to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque guidance when securing structural or load-bearing assemblies.
