Sargent 01-1143 US2C Machine Screw - Package of 12
The Sargent 01-1143 is a genuine OEM Machine Screw designed for the secure mounting of Sargent’s flagship heavy-duty door closers. These high-tensile fasteners are specifically engineered for use with thru bolts [link] or threaded anchors (such as Rivnuts or Molly Jack Nuts). Featuring a US2C (Zinc Plated) finish for corrosion resistance, these screws provide the structural foundation required to handle the extreme spring tension and closing forces of Grade 1 hardware.
Institutional Grade Features
- Universal Closer Compatibility: The standard mounting screw for Sargent’s most popular heavy-duty closers, including the 351, 281, and 1431 series.
- Optimized Length Logic: At approximately 1/8" longer than a standard hinge screw, the 01-1143 provides the necessary thread depth to engage securely with thru bolts or internal anchors without bottoming out.
- Heavy-Duty Anchor Support: Specifically designed for use with 12-24 threaded anchors, making them the ideal choice for hollow metal doors or mineral-core wood doors where standard wood screws would fail.
- Direct OEM Replacement: Ensures the closer body remains immovable, preventing the "closer bounce" that leads to fluid leaks and mechanical failure.
- Convenient 12-Pack: Provides enough hardware for a full closer installation with extra spares for maintenance kits.
