Rockwood SP1025 Single Cone Head Machine Screw | 1/4-20 x 2-1/4"
The Rockwood SP1025 is a precision-engineered replacement fastener designed specifically for Type 5 back-to-back mounting systems. This single cone head machine screw is the essential hardware for linking two straight door pulls through the door, providing a secure, stable connection. Sized for standard 1-3/4" thick commercial doors, it ensures your architectural handles remain firmly attached even under the stress of high-frequency daily use.
Professional Grade Mounting & Reliability
- Type 5 Back-to-Back Performance: Specifically manufactured for Rockwood’s Type 5 mounting configuration. This screw passes through the door to act as the primary anchor for the interior and exterior handles.
- Stable Cone Head Design: The tapered cone head provides a positive seat for the door pull, distributing pressure evenly to prevent the handle from wobbling or damaging the door surface.
- Standard 1-3/4" Door Compatibility: With a 2-1/4" thread length and a 2-3/4" overall length, this screw is precision-sized for standard wood and hollow metal commercial doors.
- Heavy-Duty Construction: Made from durable, zinc-coated steel to resist corrosion and provide the shear strength necessary for oversized or heavy commercial pulls.
- Seamless Architectural Fit: Designed to work behind the scenes, allowing for a clean installation where the primary mounting hardware is hidden once the handles are secured.
