Hex socket PEEK screw

Hex socket PEEK screw

Core Features

  • High-Torque Internal Drive: Features a deep internal hexagon socket (Allen drive) designed to handle significantly higher installation torque than slotted or Phillips drives without cam-out or tool slippage.
  • Space-Saving Cap Profile: The cylindrical head design allows the screw to be installed into counterbored holes, sitting flush with or below the surface of the mating material where a standard wrench cannot reach.
  • High-Performance Virgin PEEK: Manufactured from 100% Polyether ether ketone, maintaining exceptional dimensional stability and mechanical strength in continuous operating temperatures up to 250°C (482°F).
  • Absolute Chemical Inertness: Completely immune to rust, oxidation, and galvanic corrosion. It resists degradation from a vast spectrum of aggressive chemicals, including strong acids, bases, and organic solvents.
  • Electromagnetic Transparency: 100% non-magnetic, radiolucent, and an excellent electrical insulator, preventing short circuits and signal interference in highly sensitive analytical equipment.

At Kriloha Ltd., we understand that advanced engineering often requires maximum clamping force in minimal space, all within hostile operating conditions. Our Hex Socket PEEK Screws are our engineered answer for “High-Torque-Precision” and “Compact-Environmental-Immunity.” As a premier provider of advanced polymer components, Kriloha has developed a specialized line of socket cap fasteners that balances immense mechanical holding power with the absolute environmental isolation required for frontier manufacturing.

The engineering of our hex socket series is based on Drive-Wall Fortification and Space-Optimization. Because the internal hex drive takes the brunt of the rotational force, we utilize advanced injection molding and secondary micro-machining to ensure the hex cavity is perfectly formed and structurally dense. This allows technicians to achieve maximum permissible torque without stripping or rounding out the polymer drive. At Kriloha, we verify that our thread pitches are cut to exacting tolerances to ensure a flawless, anti-galling fit. This creates a “Failure-Resistant” fastening system that secures your dynamic components deep within counterbored recesses without rusting, conducting, or degrading.

Manufacturing these advanced polymer components involves strict Dimensional and Thermal Verification. We ensure that every screw provides the reliable, creep-resistant performance required for ultra-high vacuum (UHV) and high-temperature applications. Whether you are assembling the tight internal tolerances of a high-Tesla MRI machine or securing the flanges of a chemical vapor deposition (CVD) chamber, Kriloha PEEK Screws provide the exact environmental durability your facility demands. By choosing Kriloha Ltd., you are investing in a “Future-Proof” material technology that secures your highest-value innovation.

Primary Use Cases

  • Semiconductor Manufacturing: Fastening components in wafer-handling systems and Ultra-High Vacuum (UHV) environments where low outgassing and chemical purity are mandatory.
  • Medical & Diagnostic Imaging: Ideal for the structural assembly of MRI machines, CT scanners, and diagnostic beds where non-magnetic properties and radiolucency are required for safe operation.
  • Compact Robotics & Automation: Securing actuators and internal linkages in confined spaces where flush-mounted, high-torque fastening is critical.
  • High-Voltage Electronics: Providing high-strength, non-conductive mechanical fastening in electrical panels, large transformers, and battery enclosures.
  • Analytical Laboratory Equipment: Securing casing and fluid-handling components in liquid chromatography (HPLC) systems exposed to corrosive reagents.

Frequently Asked Questions

  1. Why choose a Hex Socket cap screw over a standard Outer Hex bolt?

A hex socket cap screw has a cylindrical head with an internal drive. This allows the screw to be installed in tight, counterbored holes where a standard external wrench cannot reach the outside of the head, saving highly valuable space in compact assemblies.

  1. How do I prevent stripping the internal hex socket?

While PEEK is incredibly strong, it is a polymer. It is absolutely critical to use a high-quality, correctly sized hex key (Allen wrench) that is fully seated into the bottom of the socket before turning. Furthermore, you must adhere to specific thermoplastic torque guidelines and never over-tighten.

  1. Do these screws outgas in a vacuum environment?

No. PEEK has exceptionally low outgassing properties, making these fasteners highly suitable for Ultra-High Vacuum (UHV) environments commonly found in semiconductor manufacturing, laboratory research, and aerospace engineering.

  1. Can this screw withstand repeated sterilization cycles?

Yes. PEEK maintains its structural and dimensional integrity through thousands of repeated sterilization cycles, including high-temperature steam autoclaving, gamma radiation, and ethylene oxide (EtO) exposure, making it an industry standard for reusable medical devices.

  1. Does Kriloha offer matching PEEK nuts and washers?

Yes. To ensure maximum performance and prevent damage to mating surfaces, we highly recommend pairing these screws with Kriloha PEEK flat washers to distribute the clamping load evenly, especially if the screw is not being installed into a pre-tapped hole.
