Advantages of Metric Fasteners

Universally applicable, with exceptional versatility

China, Europe, Japan and South Korea, along with most industrialised nations, utilise the metric system, ensuring seamless exportation, compatibility and maintenance.

Standardised specifications, excellent interchangeability

Dimensions, pitch, and strength grades conform to unified national/ISO standards. M bolts and nuts produced by different manufacturers are directly interchangeable, requiring no specific equipment or brand selection.

Clear strength grades, straightforward selection

4.8, 8.8, 10.9, 12.9 grades are clearly distinguished at a glance, directly corresponding to light-duty, heavy-duty, and high-intensity applications – no pitfalls to fall into.

Precise dimensions, stable installation

Tooth profile 60°, with tight meshing, strong locking force and resistance to slippage, ensuring even force distribution and reliable safety.

Convenient procurement, lower costs

High production volumes and a mature supply chain mean everything from miniature screws to large-gauge high-strength bolts can be readily procured at excellent value for money.

Simple maintenance, hassle-free after-sales service

Should equipment break down, metric fittings can be sourced from any hardware shop without the need for customisation, re-drilling, or production delays.
