Hager 1-800-7275 US4 Commercial Hinge Machine Screws | 12-24 x 1/2" | Package of 12 or 100
The Hager 1-800-7275 is the professional’s choice for mounting architectural hinges to metal door frames when a refined, classic aesthetic is required. These Flat Phillips Head Machine (FPHM) screws are precision-engineered to provide a flush, secure fit for commercial hinges. Finished in a professional US4 Satin Brass, these fasteners are designed to coordinate perfectly with satin brass-finished hardware in high-end office suites, boutique retail spaces, and hospitality environments.
Architectural Quality and Precise Engineering
The Hager 1-800-7275 features a 12-24 thread, the universal industry standard for hollow metal frames and reinforced aluminum storefronts. The 1/2-inch length is specifically gauged to provide maximum thread engagement into the frame reinforcement without bottoming out. Sold in a convenient package of 12 or 100, these screws provide a complete fastening solution for a standard three-hinge commercial door opening.
High-Torque Performance
To ensure a secure and permanent seat, these screws are designed for use with a #3 Phillips Driver Bit. The larger drive size allows for superior torque application compared to standard #2 residential screws, significantly reducing the risk of stripping or cam-out during high-pressure installation. The countersunk head is machined to seat perfectly flush with the hinge leaf, ensuring the door operates smoothly without any fastener interference.
