Hexagon socket set PEEK screw

Hexagon socket set PEEK screw

Core Features

  • Headless “Zero-Clearance” Design: As a true set screw (often called a grub screw), it is fully threaded and features no protruding head, allowing it to sit completely flush or countersunk within the mating part.
  • Internal Hex Drive: Driven by a standard Allen key (hex wrench), providing excellent torque transfer and minimizing the risk of slipping or cam-out in tight spaces.
  • Virgin PEEK Polymer: Manufactured from Polyether ether ketone, offering exceptional mechanical strength, dimensional stability, and continuous temperature resistance up to 250°C (482°F).
  • Non-Marring Engagement: Unlike hardened steel set screws that permanently bite into and damage shafts, PEEK set screws securely clamp without galling or scoring softer metal or plastic mating surfaces.
  • Absolute Chemical & Electrical Inertness: 100% non-magnetic, radiolucent, electrically insulating, and completely resistant to harsh acids, bases, and organic solvents.

At Kriloha Ltd., we understand that securing rotating assemblies in hostile environments requires a fastener that won’t compromise the system. Our Hexagon Socket Set PEEK Screws are our engineered answer for “Flush-Profile-Locking” and “Non-Destructive-Clamping.” As a premier provider of advanced polymer components, Kriloha has developed a specialized line of set screws that balances mechanical holding power with the absolute environmental immunity required for frontier engineering.

The engineering of our PEEK set screw series is based on Drive-Socket Integrity and Thread-Pitch Precision. Because the hex socket is internal, it takes the brunt of the rotational force. We utilize advanced injection molding and secondary micro-machining to ensure the hex cavity is perfectly formed, allowing technicians to achieve maximum permissible torque without stripping the polymer drive. At Kriloha, we verify that our threads are cut to exacting tolerances to prevent the “backing-out” caused by vibration. This creates a “Failure-Resistant” locking system that secures your dynamic components without rusting, conducting, or degrading.

Manufacturing these advanced polymer components involves strict Dimensional and Thermal Verification. We offer these with various point geometries (typically flat or cup point) to match the specific engagement needs of your shaft. Whether you are assembling an ultra-pure chemical dosing pump or securing delicate optics in a laser array, Kriloha PEEK Set 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 innovations.

Primary Use Cases

  • Precision Robotics & Automation: Securing gears, pulleys, and collars to shafts in compact assemblies where space constraints prohibit the use of headed fasteners.
  • Analytical Chemistry (HPLC): Fastening components in liquid chromatography systems where absolute chemical purity and inertness are mandatory to prevent sample contamination.
  • Semiconductor Manufacturing: Utilized in wafer handling and Ultra-High Vacuum (UHV) environments due to PEEK’s exceptionally low outgassing properties.
  • Medical & Surgical Devices: Ideal for biocompatible assemblies and diagnostic imaging machines (MRI) where metal interference is strictly prohibited.
  • High-Voltage Enclosures: Acting as insulating stand-offs or locking mechanisms in electrical panels where metal screws would create arcing or short-circuit hazards.

Frequently Asked Questions

  1. What is the difference between a “Set Screw” and a standard screw?

A set screw is completely headless and is threaded all the way end-to-end. It is designed to be screwed into one object to press against (or into) another object, typically to prevent relative motion, such as locking a pulley onto a motor shaft.

  1. Why use a PEEK set screw instead of a stainless steel one?

Steel set screws can bite into and permanently damage softer shafts (like aluminum), making disassembly difficult. PEEK set screws hold firmly but are “non-marring,” protecting your expensive machined shafts. Additionally, PEEK provides electrical insulation and chemical resistance that steel cannot match.

  1. Are different “points” available for the tip of the screw?

Yes. While the standard is often a “Flat Point” (best for flat shafts and preventing damage), Kriloha can manufacture “Cup Point” or “Cone Point” variations depending on whether you need a smooth friction-hold or a more aggressive bite into a pre-drilled dimple.

  1. How much torque can the internal hex drive handle?

While PEEK is one of the strongest thermoplastics, it is still a polymer. It is crucial to use a properly sized, high-quality hex key and adhere strictly to maximum torque guidelines to prevent rounding out the internal hex socket.

  1. Can these screws be sterilized for medical applications?

Absolutely. PEEK maintains its structural integrity through repeated sterilization cycles, including autoclaving (steam), gamma radiation, and ethylene oxide (EtO) exposure, making it ideal for reusable surgical equipment.
