These screws are more reliable in high-stress, high-temperature environments than other plastic screws. They withstand water, steam, and temperatures up to 500°F. They're angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.

PEEK has high-temperature resistance, radiation resistance, corrosion resistance, good dimensional stability, excellent electrical properties, etc., but also has excellent processing properties, easy injection molding, extrusion molding, and cutting, and is one of the best overall performance of the unique engineering plastics, at the top of the pyramid of plastic materials. Polyether ether ketone (PEEK) resin is a unique engineering plastic with excellent performance. Compared with other special engineering plastics, they have more significant advantages: high-temperature resistance, excellent mechanical properties, good self-lubricating, chemical corrosion resistance, flame retardant, peel resistance, abrasion resistance, not tolerate nitric solid acid, concentrated sulfuric acid, radiation resistance, super mechanical properties can be used in high-end machinery, nuclear engineering and aerospace and other technologies.

Irradiation resistance, insulation stability, hydrolysis resistance, pressure resistance, corrosion resistance, and composite materials are utilized to create mechanical parts with a self-lubricating effect, offering temperature resistance, good thermal stability, and ultra-high heat resistance (exceeding that of PPS).

1. Mechanical properties: PEEK is an inflexible, rigid, and balanced plastic. Its excellent fatigue resistance to alternating stress is the most outstanding of all plastics, comparable to alloy materials.

2. Self-lubricating: PEEK is used in all plastics and has outstanding sliding characteristics. It is suitable for the strict requirements of low coefficient of friction and wear-resistant use. Carbon fiber and graphite contributed to a certain percentage of the mixed modified PEEK's self-lubricating performance.

3. Chemical resistance (corrosion resistance): PEEK has excellent chemical resistance. The usual chemicals that can dissolve or destroy it are concentrated sulfuric acid; its corrosion resistance is similar to nickel steel.

4: Flame retardant: PEEK is a very stable polymer with 1.45mm thick samples, and without adding any flame retardant, it can reach the highest flame retardant standards.

5. Stripping resistance: PEEK has excellent stripping resistance, so it can be made into a skinny wrap or electromagnetic wire and used in harsh conditions.

6. Fatigue resistance: PEEK has the best fatigue resistance among all resins.

7. Irradiation resistance: PEEK has the best fatigue resistance among all resins. 7. Irradiation resistance: PEEK can withstand high irradiation, exceeding the best irradiation resistance of polystyrene in general-purpose resins. It can be subjected to a γ irradiation dose of up to 1100 Mrad and retains its high-performance insulation ability.

8. Hydrolysis resistance: PEEK and its composite materials are not subject to the chemical influence of water and high-pressure water vapor; with this material made of products in high temperature and high-pressure water, continuous use can maintain excellent characteristics.
