Match bolt thread specification among M3 to M16 before starting assembling operations.
Confirm corresponding pitch size for each specification to avoid forced screwing into place.
Use matching open spanner for tightening to avoid scratch on hexagonal outer edges.
Keep spare nuts placed in dry surroundings to limit abnormal change on inner thread parts.
Do not apply excessive torque while fastening to avoid inner thread deformation.
Description
Hex weld nuts adopt carbon steel raw material for mechanical and metal workpiece mounting work.
Full metric sizes from M3 up to M16 carry matched standard pitch for regular accessory pairing.
Special edge structure helps fix the component onto metal pieces via welding process.
Standard inner thread works well with common metric bolts across various equipment fitting jobs.
Fit metal frame fabrication, cabinet production and multiple DIY metal processing projects.
