3/8UNF Imperial Grub Screws
Description
Grub Screw – 3/8 UNF Stainless Steel
Our 3/8" UNF Grub Screws (also known as socket set screws) are precision-engineered headless fasteners designed for secure, internal clamping in high-tolerance mechanical assemblies. These screws sit flush within the tapped hole, providing a clean, obstruction-free finish—ideal for locking shafts, gears, collars, and other components in place without interfering with moving parts.
The 3/8" UNF (Unified National Fine) thread offers enhanced tensile strength and superior resistance to vibration, making these screws ideal for critical applications in precision machinery, automotive, and aerospace environments. The fine thread allows for secure fastening in harder materials or where thread engagement depth is limited.
Equipped with a hex socket drive, these screws are easily installed using an Allen key, delivering consistent torque and reducing the risk of stripping. Crafted from corrosion-resistant stainless steel, they are well-suited for use in harsh environments exposed to moisture, chemicals, or temperature changes.
Whether used for detailed assembly or critical component retention, our 3/8 UNF Grub Screws offer the strength, precision, and clean finish demanded by professional applications.
