1/2BSW Imperial Grub Screws
Description
Grub Screw – 1/2 BSW Stainless Steel
Our 1/2" BSW Grub Screws (also known as socket set screws) are engineered for secure, headless fastening in demanding mechanical applications. Designed to be fully threaded and sit flush within the material, these screws are ideal for situations where a clean surface profile and strong internal hold are essential—such as locking shafts, collars, or pulleys in place.
The 1/2" BSW (British Standard Whitworth) coarse thread provides reliable grip and compatibility with legacy British-threaded components, making it suitable for restoration, heavy machinery, and industrial applications.
Featuring a hex socket drive, these grub screws are easy to install with an Allen key, allowing for strong torque transfer and a tight, vibration-resistant hold. Made from corrosion-resistant stainless steel, they are suitable for use in harsh environments, including exposure to moisture, oils, and chemicals.
Ideal for use in engineering, maintenance, and mechanical systems, these 1/2 BSW grub screws provide a durable, low-profile solution for secure internal fastening.
