M12x110 outer hexagon PEEK screw

M12x110 outer hexagon PEEK screw

  • Heavy-Duty Extended Sizing: Features an M12 thread diameter and a substantial 110mm shank length, specifically designed for deep structural fastening, securing thick flanges, or clamping multiple layers of material simultaneously.
  • Standard Outer Hexagon Head: The traditional external hex profile allows for maximum torque transmission using standard metric wrenches or sockets, making it ideal for heavy-duty assembly where high clamping force is required.
  • High-Performance Virgin PEEK: Manufactured from 100% Polyether ether ketone, providing an exceptional strength-to-weight ratio and maintaining mechanical integrity in continuous operating temperatures up to 250°C (482°F).
  • Absolute Chemical Inertness: Completely immune to rust, oxidation, and galvanic corrosion. It remains unaffected by continuous exposure to harsh acids, bases, saltwater, and aggressive organic solvents.
  • Electromagnetic Transparency: 100% non-magnetic, radiolucent, and highly electrically insulating, completely eliminating the risk of short circuits, arcing, or signal interference in sensitive high-energy environments.

At Kriloha Ltd., we understand that deep-structural fastening in corrosive or high-voltage environments pushes standard materials beyond their limits. Our M12x110 Outer Hexagon PEEK Screws are our engineered answer for “Deep-Penetration-Clamping” and “Total-Environmental-Immunity.” As a premier provider of advanced polymer components, Kriloha has developed a heavy-duty PEEK fastener line that delivers the sheer mechanical holding power required for massive industrial assemblies without the vulnerabilities of metal.

The engineering of our extended-length PEEK series is based on Tensile-Load-Distribution. A 110mm bolt spans a significant distance, making it susceptible to shear and bending forces. By utilizing advanced injection molding combined with precision secondary machining, we ensure the M12 thread pitch is perfectly uniform across the entire length, preventing the binding or galling that typically plagues long fasteners. At Kriloha, we verify that the outer hexagonal head is fortified to handle the high rotational forces required to seat a 110mm bolt, creating a “Failure-Resistant” locking system that secures your largest components without rusting, conducting, or degrading.

Manufacturing these advanced polymer components involves strict Dimensional, Straightness, and Thermal Verification. We ensure that every long-shank screw provides the reliable, creep-resistant performance required for ultra-high vacuum (UHV) and heavy chemical applications. Whether you are assembling the structural frame of a high-Tesla MRI or clamping high-pressure chemical transfer pipes, 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 most substantial industrial assets.

Primary Use Cases

  • Chemical Processing Flanges: Bolting together thick, large-diameter pipe flanges and heavy-duty fluid valves where steel bolts would rapidly succumb to chemical corrosion.
  • Medical & Diagnostic Imaging: Providing deep structural support for the frames of MRI and CT machines where absolute non-magnetic (RF transparent) properties are legally required.
  • Semiconductor Manufacturing: Fastening heavy vacuum chamber bulkheads and clean-room equipment where low outgassing and high chemical purity are mandatory.
  • Marine & Subsea Infrastructure: Securing underwater sensors and structural housings; PEEK absorbs virtually no moisture and is completely immune to saltwater degradation.

High-Voltage Power Distribution: Acting as a high-strength, non-conductive structural tie in massive electrical transformers and high-capacity battery storage banks.

Frequently Asked Questions

  1. What do the dimensions “M12x110” specifically mean?

“M12” denotes a standard metric thread diameter of 12 millimeters. “110” signifies that the length of the threaded shank, measured from directly underneath the hex head to the very tip of the screw, is exactly 110 millimeters.

  1. Is the 110mm shank fully threaded or partially threaded?

Depending on the specific industrial requirement, Kriloha offers these both as fully threaded bolts (for maximum adjustability) and partially threaded bolts (featuring a smooth shoulder under the head to increase shear strength in deep bore holes).

  1. Why use an outer hex head instead of a hex socket for a bolt this size?

An outer hexagon head allows for the use of heavy-duty external sockets and long-handled wrenches, providing superior leverage and torque transmission compared to an internal socket drive, which is vital when driving a long 110mm bolt through thick materials.

  1. How much torque can I safely apply to an M12 PEEK bolt?

While the M12 gauge is highly robust, PEEK is a thermoplastic. It cannot be torqued to the extreme specifications of a Grade 8 steel bolt. You must strictly adhere to specific PEEK torque guidelines and use a calibrated torque wrench to prevent stretching the bolt or stripping the threads.

  1. Does Kriloha recommend using nuts and washers with this long bolt?

Absolutely. For a bolt of this length, we highly recommend pairing it with Kriloha M12 PEEK nuts and wide flat washers on both ends of the assembly. This distributes the massive clamping load evenly and prevents the hex head and nut from digging into softer mating flanges.
