Product description

Compiled from the existing technical description of this product on this site

The TORX nylon-patch locking screw has a Nylok-type nylon locking patch pre-applied to the thread. When driven in, the patch is compressed and produces continuous radial spring-back resistance, forming a friction-torque lock that can be assembled and disassembled repeatedly. Compared with chemical locking adhesives, the nylon patch does not cure and does not contaminate the thread, so the same screw keeps effective locking over many assembly cycles.

Technical Features
Pre-applied nylon adhesive keeps the locking torque after more than ten re-assembliesNo adhesive application on site: fewer assembly steps and a stable cycle timeTorx drive combines high torque transmission with cam-out resistanceCold heading plus precision thread rolling: full thread form and consistent dimensionsSuited to automated lines with stable feeding and driving
Applications
Automated production line equipmentIndustrial fans and pumpsPower tools and garden machineryAutomotive parts

FAQ

Material, standards, surface treatment and installation points for this model; the data comes from the specification table on this page and from the national standards cited in the answers.

Q1What material is the Torx cheese-head nylon-adhesive anti-loosening screw available in, and what strength level does it reach?

Material specified in this page's specification table: premium alloy steel. Mill certificates and mechanical property test reports can be provided with the shipment; batch acceptance follows the specifications above.

Q2To which standard is the Torx cheese-head nylon-adhesive anti-loosening screw produced and accepted?

Standards marked in the specification table on this page: thread GB/T 196, GB/T 197 (ISO 965-1) 6g; mechanical properties GB/T 3098.1 (ISO 898-1); drive ISO 10664; pre-applied nylon patch locking per company standard. Dimensional inspection reports can be supplied with the shipment; batch acceptance follows the standards above and the drawings agreed by both parties.

Q3Which surface treatments are available for the Torx cheese-head nylon-adhesive anti-loosening screw, and how to choose?

Surface treatment marked in the specification table on this page: black oxide / zinc plated (optional). Each coating differs in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.

Q4Where is the Torx cheese-head nylon-adhesive anti-loosening screw used?

Typical applications listed in the product description on this page: automated production line equipment; industrial fans and pumps; power tools and garden machinery; automotive components. Overview: the TORX nylon-patch locking screw has a Nylok-type nylon locking patch pre-applied to the thread; when driven in, the patch is compressed and produces continuous radial spring-back resistance, forming a friction-torque lock that can be assembled and disassembled repeatedly.

Q5What is the locking principle of pre-applied adhesive parts such as the Torx cheese-head nylon-adhesive anti-loosening screw?

A viscoelastic adhesive layer is pre-applied to the threaded section. After the screw is driven in, the adhesive fills the gaps between the thread flanks and gives the thread pair continuous damping and adhesion, suppressing back-rotation. Residual locking capacity remains after re-assembly, but it decreases with the number of assembly cycles. The pre-application process follows the company standard; the thread is GB/T 196, GB/T 197 6g. (Applies to this model: “TORX nylon-patch locking screw”.)
