Hager 1-350-9073 US2C Zinc Security Spanner Machine Screws | 12-24 x 1/2" | Package of 24
The Hager 1-350-9073 is the industry-standard security fastener for protecting architectural hardware in high-traffic or high-security commercial environments. These Flat Head Spanner Machine Screws are designed to prevent unauthorized removal of hinges and strikes, requiring a specialized driver for installation and adjustment. Finished in US2C Zinc, these screws provide a professional, durable look that coordinates seamlessly with US26D Satin Chrome hinges.
Security-Grade Hardware Protection
In public facilities like schools, transit hubs, and government buildings, standard Phillips screws are vulnerable to tampering. The Hager 1-350-9073 utilizes a #12 Spanner (snake-eye) drive, providing a significant deterrent against vandalism. These screws are manufactured from high-strength steel to ensure they can withstand the rigors of heavy-duty commercial door cycles without loosening or failing.
Universal Commercial Compatibility
Sized at the universal 12-24 thread pattern with a 1/2-inch length, these fasteners are highly versatile. They are the standard machine screw used for 4", 4-1/2", and 5" commercial grade hinges, including both standard and heavy-weight configurations. Additionally, they are the preferred security upgrade for securing standard ASA 4-7/8" commercial strike plates in metal frame applications.
