Product description

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

The TORX cheese head three-part locking screw assembly consists of a screw, a spring washer and a plain washer riveted at the factory into one unit that cannot come apart. The TORX® recess transmits higher torque at the same head diameter and resists cam-out, and together with the pre-applied thread adhesive it suits automated batch assembly of precision equipment.

Technical Features
Bolt + spring washer + flat washer in one three-part assembly, ruling out missing or lost washersThe Torx drive has a large load-bearing area; high-torque tightening neither slips nor damages the recessThread pre-coated with locking adhesive: resists vibration loosening and allows repeated reworkStable height tolerance after assembly, suiting pick-up by automatic driving equipmentThread length, head style and adhesive type made to drawing
Applications
Precision electronics and optical equipmentDriving stations on automated linesIndustrial control cabinets and enclosuresAutomotive electronics modules

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 three-part anti-loosening screw available in, and what strength level does it reach?

Marked in the specification table on this page: material is high-strength alloy steel. Material certificates and mechanical property test reports can be supplied with the goods; batch acceptance follows the data above.

Q2Which surface treatments are available for the Torx cheese-head three-part anti-loosening screw, and how to choose?

The specification table on this page lists surface treatments: black oxide / zinc plated / zinc-nickel alloy (optional). Different coatings differ in appearance, corrosion resistance and cost; choose according to the service environment and order agreement.

Q3Where is the Torx cheese-head three-part anti-loosening screw used?

Typical applications listed in this product description: precision electronics and optical equipment; automated assembly-line locking stations; industrial control cabinets and enclosures; automotive electronics modules. Overview: the Torx cylindrical head 3-piece lock screw combines a screw, a spring washer and a flat washer into one unit, riveted at the factory into a single assembly whose parts cannot scatter.

Q4What are the head type, drive and structure of the Torx cheese-head three-part anti-loosening screw?

Head type specified in this page's specification table: Torx; drive: Torx. Structural details are subject to the drawing.

Q5What is the locking principle of pre-applied adhesive parts such as the Torx cheese-head three-part 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 cheese head three-part locking screw assembly”.)
