Peek Fasteners
Caliber Enterprise is a leading Peek Fasteners Manufacturer that produces high-quality fasteners produced using Polyether Ether Ketone (PEEK), which has a good chemical resistance, thermal stability, and mechanical strength. Such fasteners are common in the aerospace, automotive, medical, and electronics industry where a high level of durability and reliability in extreme conditions is needed. Peak Fasteners have better performance in wear, high temperature and aggressive chemicals and gives long and reliable connection with critical assemblies.
| Material | Grade / Standard | Fastener Type | Size Range | Thread Standard | Continuous Service Temp (°C) | Key Properties | Approx. Weight Basis |
|---|---|---|---|---|---|---|---|
| PEEK (Polyether Ether Ketone) | ASTM D6262 | Bolt | M3–M20 | Metric | up to 250 | High strength-to-weight, chemical resistant | Size dependent |
| PEEK (Unfilled) | ASTM D6262 | Nut | M3–M20 | Metric | up to 250 | Electrically insulating, non-magnetic | Size dependent |
| Glass-Filled PEEK | ASTM D6262 GF30 | Screw | M4–M16 | Metric | up to 260 | Improved stiffness, creep resistance | Size dependent |
| Carbon-Filled PEEK | ASTM D6262 CF30 | Stud | M6–M24 | Metric | up to 300 | Enhanced wear, low thermal expansion | Size dependent |
| PEEK (Unfilled) | ASTM D6262 | Washer | M3–M30 | Metric | up to 250 | Low outgassing, lightweight | Size dependent |
PEEK fasteners find application in areas where metal fasteners cannot be deployed including semiconductor equipment, aerospace interior, medical equipment, and also chemical processing systems that need lightweight, non-conductive, and high temperature resistant parts. The choice of material (unfilled, glass-filled, or carbon-filled) directly affects the performance of stiffness, creep, and wear performance, and are usually considered in conjunction with PEEK Nut Bolts in order to have the same thermal and mechanical behavior through the assembly. On a B2B Marketplace, the grades, service temperature, and property differentiation are listed in detailed tables to enable the engineers and buyers assess appropriateness within a short time and select rapid solutions in accordance with the challenging operating conditions.
