Hager 1-803-2499 US32D Stainless Steel Hinge Machine Screws | 12-24 x 1/2" | Package of 12
The Hager 1-803-2499 is the professional standard for mounting architectural hinges in corrosive environments or high-moisture areas. These Flat Phillips Head Machine (FPHM) screws are manufactured from high-grade stainless steel, providing the ultimate defense against rust and oxidation. Finished in US32D (Satin Stainless Steel), these fasteners are designed to coordinate perfectly with stainless steel hinges on hospital doors, laboratory entrances, and coastal commercial properties.
Corrosion Resistance and Industrial Strength
Unlike standard plated steel fasteners, the Hager 1-803-2499 is made of solid stainless steel, ensuring the structural integrity of your door hardware even in harsh conditions. The 12-24 thread is the universal industry standard for hollow metal frames, and the 1/2-inch length provides maximum thread engagement without bottoming out. Sold in a package of 12, these screws are the ideal choice for hanging a standard three-hinge commercial door where longevity and durability are paramount.
Precision Engineering and Versatility
Designed for a wide range of hardware, these screws are compatible with 4", 4-1/2", and 5" commercial grade hinges, whether in standard or heavy-weight configurations. For a secure, permanent seat, they require a #3 Phillips Driver Bit, which allows for higher torque and prevents stripping during installation. Beyond hinges, these fasteners are the preferred choice for securing standard ASA 4-7/8" commercial strike plates to metal frames.
