Product description

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

The Torx socket locking screw is precision cold-headed from quality alloy steel, with a nylon patch pre-applied on the thread; the resilient friction of the compressed patch prevents loosening. The nylon does not cure or contaminate the thread and allows repeated assembly and disassembly, making it ideal for fastening points on automated lines that need frequent maintenance.

Technical Features
Pre-applied nylon locking patch, still effective after repeated assembly and disassemblyTorx drive, high torque transmission and cam-out resistantPrecise cold heading + thread rolling, full and uniform threadsNo on-site dispensing, simplified assembly processSuitable for automated feeding and driving on production lines
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 Lock Screw made of, and what strength level does it achieve?

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.

Q2What manufacturing process is used for the Torx Lock Screw?

The specification table on this page states the process as cold heading. The process route follows drawing and order requirements; first-article approval is provided before volume production.

Q3What are the main features of the Torx Lock Screw?

Features listed in this page's product description: pre-applied nylon threadlocker that remains effective after repeated assembly; Torx recess with high torque transfer and cam-out resistance; precision cold heading + thread rolling for full, consistent threads; no on-site adhesive dispensing required, simplifying the assembly process.

Q4To which standards is the Torx Lock Screw manufactured and inspected?

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.

Q5What does the 6g thread tolerance of the Torx Lock Screw mean?

6g is the standard tolerance class for external threads (GB/T 197 / ISO 965-1). It defines the manufacturing tolerance range for the pitch diameter and major diameter, balancing smooth engagement against manufacturing economy; the mating internal thread is usually 6H. All threads in this series are inspected to 6g. (Applies to model "Torx socket locking screw".)
