1. Core material characteristics
The raw material is pure PEEK (polyetheretherketone) high-performance engineering plastic. It is original light beige without added recycled material and without glass fiber addition. Optional without glass fiber doping; The material has high strength and rigidity, with tensile strength comparable to that of metals, not prone to breaking, and at the same time has the toughness of plastics, with no brittle fracture during impact.
2. Fastening component process characteristics
Internal hexagonal cylindrical head bolt: The head has vertical ridges for anti-slip design, the internal hexagonal hole is evenly stressed, it is not easy to slip when tightening, the full tooth precision rolling thread has uniform depth of the pattern, and the pattern fits tightly with the nut; The large-sized M10 bolt has strong bearing capacity and is suitable for the fixation of heavy equipment.
Crossed flat head screw: The cross groove is evenly stressed, compatible with ordinary cross screwdrivers, the short-sized is suitable for the installation of micro-precision components, the head is flat and fits closely with the workpiece, without scraping the internal components of the equipment.
PEEK hexagonal nut: Standard hexagonal shape, six flat surfaces are easy to be held by a wrench, the internal thread has standard tolerance, and it perfectly meshes with the same-sized bolt, locking is not prone to deviation.
PEEK flat washer: The same material washer evenly disperses the locking pressure, prevents the surface of the workpiece from being damaged, and isolates the contact surface of the two materials to avoid friction loss.
3. Overall physical characteristics
Flame-retardant and self-extinguishing, it will not continue to burn when exposed to open flames, and no toxic smoke is released;
Strong dimensional stability, in high-temperature environments, the expansion and deformation are extremely small, and it will not loosen after long-term fixation;
No metal burrs, after assembly, it will not scratch precision components, films, and glass-like parts.

Extremely high temperature resistance, stable performance in both high and low temperature conditions
PEEK special engineering plastic has extremely high temperature resistance. Its long-term working temperature can reach 260℃, and it can withstand 315℃ high temperature for a short period. It will not crack or deform in low-temperature environments. It can be securely fastened in high-temperature ovens, heat-melting equipment, and low-temperature freezing equipment for long-term stability. Metal screws cannot be used in this extreme temperature difference scenario.
Fully insulated and non-magnetic, eliminating conductive interference
The overall material is non-metallic, non-conductive, and non-magnetic. It does not generate electromagnetic eddy currents or short-circuit leakage risks. It will not interfere with precision instruments or electromagnetic equipment signals. It is perfectly suitable for the assembly of electronics, semiconductors, and nuclear magnetic equipment, avoiding the electromagnetic interference and conductive short-circuit hazards caused by metal fasteners.
Super strong corrosion resistance, resistant to various chemical media
Resistant to strong acids, strong alkalis, organic solvents, salt water, and oil-based media. It does not rust or oxidize. Long-term immersion in chemical solutions, seawater, and cleaning solutions will not cause corrosion and damage. Compared to stainless steel screws, it can cope with harshly corrosive chemical production environments and does not have the problem of rusting and getting stuck.
Lightweight and low friction, long-lasting wear resistance
The density is much lower than that of stainless steel, significantly reducing the overall weight of the equipment. It has self-lubricating properties, with a low friction coefficient. It is less likely to wear the threads during repeated disassembly and dynamic operation. No additional lubricating oil is needed. The threads will not easily slip or break over a long period of use.
Food and medical grade safety, excellent biocompatibility
The original pure PEEK material is non-toxic and does not leach. It complies with food contact and medical biological safety standards. It can be used in food processing equipment and medical diagnostic equipment assembly. It will not leach harmful substances and contaminate materials and samples.
Comprehensive size matching for complete sets, convenient assembly
Screws, nuts, and washers are factory-matched with the same material. The thread tolerance is uniform, and the fit is tight. No separate accessories need to be selected. The size specifications cover the tightening requirements of various equipment sizes. A complete set of special non-metallic fasteners is provided.
