PTFE Slotted Cheese Head Screw
PTFE slotted cheese head screw is a high-performance fluoropolymer fastener designed for applications requiring extreme chemical resistance, excellent electrical insulation, ultra-low friction, and long-term stability in harsh environments. The PTFE slotted cheese head screw is manufactured from virgin polytetrafluoroethylene (PTFE), a premium engineering material known for its outstanding resistance to nearly all industrial chemicals and wide temperature adaptability.
The PTFE slotted cheese head screw features a cylindrical cheese head with a straight slotted drive, enabling easy installation using a standard flat-head screwdriver. It is widely used in chemical processing systems, semiconductor equipment, pharmaceutical production, laboratory instruments, water treatment facilities, food processing machinery, marine engineering, and OEM industrial assemblies where corrosion-free fastening is essential.
Product Overview
The PTFE slotted cheese head screw is engineered for demanding industrial environments where conventional metal or standard plastic fasteners cannot perform reliably. Its cylindrical head provides a stable bearing surface, while the slotted drive allows simple manual or tool-assisted installation.
Compared with PVC, PA66, and PVDF fasteners, the PTFE slotted cheese head screw offers superior chemical resistance, excellent temperature stability, and extremely low friction performance. It prevents metal contamination, galvanic corrosion, and electrical conductivity issues in sensitive systems.
As a premium industrial fastener, the PTFE slotted cheese head screw is widely used in high-purity, corrosive, and temperature-sensitive applications.

Materials and Manufacturing Process
The PTFE slotted cheese head screw is manufactured using precision compression molding combined with CNC machining to achieve high dimensional accuracy and stable performance.
Production begins with virgin PTFE resin, selected for purity and chemical stability. The material is compression molded under controlled pressure and temperature to form a stable blank.
CNC machining is then used to shape the cylindrical head, slotted drive, threaded shank, and critical dimensions. For high-precision requirements, secondary machining ensures accurate thread pitch, head geometry, and length control.
Each PTFE slotted cheese head screw is cleaned to remove residues and undergoes strict inspection for dimensional accuracy, thread quality, head structure, surface condition, and packaging before shipment.
