Product description

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

The ultra-thin head locking joint screw reduces assembly space and weight with its ultra-thin head; a high-grade alloy steel body ensures strength and fatigue resistance, and the micro pre-applied locking compound prevents loosening under high-speed reciprocating motion. Precision thread rolling gives very high dimensional consistency, making it a reliable choice for narrow joint areas.

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 Lock Joint Screw (ultra-thin head, space-saving) made of, and what strength level does it achieve?

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.

Q2What applications is the Ultra-Thin Head Lock Joint Screw (ultra-thin head, space-saving) suitable for?

Typical applications listed on this page: hinges and folding mechanisms; linkages and shafts; flip parts of portable devices; precision motion modules. Overview: the ultra-thin head locking joint screw uses an ultra-thin head to reduce assembly space and weight; a high-grade alloy steel body provides strength and fatigue resistance, and the micro pre-applied locking compound keeps it from loosening under high-speed reciprocating motion.

Q3What manufacturing process is used for the Ultra-Thin Head Lock Joint Screw (ultra-thin head, space-saving)?

Thread rolling is specified as the process in this page's specification table. The process route follows drawing and order requirements; first-article approval is provided before volume production.

Q4What are the main features of the Ultra-Thin Head Lock Joint Screw (ultra-thin head, space-saving)?

Features listed in this page's product description: ultra-thin head that saves space and reduces the weight of moving parts; high-grade alloy steel with good fatigue resistance; micro anti-loosening pre-coating that stays tight during high-speed reciprocating motion; precision thread rolling for consistent dimensions and smooth assembly.

Q5What does the 6g thread tolerance of the Ultra-Thin Head Lock Joint Screw (ultra-thin head, space-saving) 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 "ultra-thin head locking joint screw (ultra-thin head, reduced space)".)
