Product description

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

The ultra-thin head locking joint screw uses a very thin head to compress the assembly space and reduce weight, and combines a high-grade alloy steel body with micro pre-applied locking to stay tight under high-speed reciprocating motion. Precision thread rolling ensures consistent thread dimensions, making it the locking fastener of choice for narrow joint locations such as hinges, shafts and linkages.

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 ultra-thin head anti-loosening articulating screw (micro locking, pre-applied) 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.

Q2To which standard is the ultra-thin head anti-loosening articulating screw (micro locking, pre-applied) 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); pre-applied locking to company standard. Dimensional inspection reports can be supplied with the shipment; batch acceptance follows the standards above and the drawing agreed by both parties.

Q3Which surface treatments are available for the ultra-thin head anti-loosening articulating screw (micro locking, pre-applied), 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 ultra-thin head anti-loosening articulating screw (micro locking, pre-applied) used?

Typical applications listed in the product description on this page: hinges and folding structures; linkages and shaft locations; precision motion mechanisms; folding parts of portable devices. Overview: the ultra-thin head locking joint screw uses a very thin head to compress the assembly space and reduce weight, and combines a high-grade alloy steel body with micro pre-applied locking to stay tight under high-speed reciprocating motion.

Q5What is the locking principle of pre-applied adhesive parts such as the ultra-thin head anti-loosening articulating screw (micro locking, pre-applied)?

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: “ultra-thin head locking joint screw (micro pre-applied locking)”.)
