PTFE Slotted Flat Point Set Screw
PTFE slotted flat point set screw is a high-performance fluoropolymer headless fastener designed for precision positioning, locking, and adjustment in extreme chemical and high-purity environments. The PTFE slotted flat point set screw is manufactured from virgin polytetrafluoroethylene (PTFE), offering outstanding chemical resistance, excellent electrical insulation, ultra-low friction, and long-term stability under harsh industrial conditions.
The PTFE slotted flat point set screw features a headless cylindrical body with a straight slotted drive and a flat point tip. This structure allows the screw to apply uniform pressure on contact surfaces while minimizing damage to mating components. It is widely used in semiconductor equipment, chemical processing systems, pharmaceutical machinery, laboratory instruments, water treatment systems, food-grade equipment, marine engineering, and OEM industrial assemblies.

Product Overview
The PTFE slotted flat point set screw is engineered for applications requiring non-metallic fastening with precise adjustment capability. The flat point design provides stable contact without sharp indentation, making it suitable for positioning shafts, collars, guide rails, and sensitive components.
Compared with PVC, PA66, and PVDF set screws, the PTFE slotted flat point set screw delivers superior chemical resistance, temperature tolerance, and non-stick performance. It is especially suitable for environments involving strong acids, strong alkalis, organic solvents, and ultra-pure media.
As a premium industrial fastener, it ensures reliable performance in corrosive, cleanroom, and electrically sensitive applications.

Materials and Manufacturing Process
The PTFE slotted flat point set screw is manufactured using precision compression molding combined with CNC machining to achieve high accuracy and stable performance.
Production begins with virgin PTFE resin, carefully selected for purity and chemical stability. The material is compression molded under controlled temperature and pressure to form a stable blank.
CNC machining is then used to form the threaded body, slotted drive, and flat point tip. Secondary machining ensures tight dimensional control for thread pitch, length, and point geometry.
After machining, each PTFE slotted flat point set screw is cleaned, inspected, and packaged under strict quality control standards to ensure consistent performance.
