PEEK Screws Nuts Washers Set, High Temperature Resistant Insulating Polyetheretherketone Fasteners, Anti-Corrosion Plastic Bolts for Semiconductor Medical Equipment

This set of fasteners is entirely made of pure PEEK (polyetheretherketone) material through injection molding and machining. It includes an external hexagonal bolt, an internal梅花-shaped cylindrical head screw， a cross-head screw， a matching hexagonal nut, and a complete set of PEEK flat washers.

PEEK is a high-end special engineering plastic. Its comprehensive performance exceeds that of nylon， PVC， and PTFE ordinary plastic screws. It combines the advantages of high temperature resistance， insulation， corrosion resistance， high strength， and self-lubrication. It is widely used in precision equipment scenarios where metal screws cannot be used. Custom specifications， head types， and sizes are supported.

Super high-temperature resistant, with long-term stable performance

The long-term working temperature can reach 260℃, and the instantaneous temperature resistance is 315℃. It will not deform, soften or lose strength under high-temperature conditions, and is suitable for ovens, injection molds, and high-temperature detection equipment.

Excellent insulation and no magnetism, no interference to electronic signals

Fully insulated and non-magnetic, it will not generate eddy currents and will not interfere with chips, sensors, circuit boards. It is specially suitable for semiconductors, medical nuclear magnetic resonance, and precision electronic instruments, eliminating the problems of metal short circuits and magnetization.

Strong resistance to chemical corrosion, resistant to various acid and alkali solvents

It can withstand strong acids, strong alkalis, organic solvents, and oils. It will not dissolve or crack in seawater and chemical liquid environments for long-term use, and is superior to stainless steel. It is preferred for chemical equipment and electroplating production lines.

High strength and high toughness, not prone to fracture or slippage

The tensile and compressive strength are close to metals, with good toughness. It is not brittle at low temperatures. The precision rolling thread has a tight fit and is not prone to slipping when repeatedly disassembled, and the load-bearing and fixation are stable.

Self-lubricating and wear-resistant, lightweight without damaging the workpiece

It has its own self-lubrication performance and no additional oil application is required. Its density is much lower than that of metals, which reduces weight and improves lightweight. When locking, it will not scratch aluminum alloys, ceramics, PCB boards and other precision workpieces.

Food and medical grade safe and non-toxic

Pure resin without precipitation, in line with food contact and biological compatibility standards, and can be used for food processing equipment, medical equipment, and assembly of implant and auxiliary devices.

Screw head type is optional

Hexagon bolt: High force, suitable for heavy equipment tightening, the M10 large-sized model in the picture

Hexagonal ribbed cylindrical head: Suitable for assembly in narrow spaces, aesthetically pleasing and integrated

Cross flat head screw: Simple assembly for thin plates and panels, convenient for disassembly and assembly

Matching accessories

Same material PEEK hexagonal nuts + PEEK flat washers, the entire set of materials are unified, with the same thermal expansion coefficient, will not loosen or get stuck due to material differences at high temperatures.

Standard threads

National standard metric threads M2/M3/M4/M5/M6/M8/M10, full range of specifications available in stock. Non-standard lengths and special head types can be customized and processed according to the drawing or sample.
