Cylindrical Locating Pin

↵

Carbon steel galvanized flat head cylindrical pin with hole (cylindrical locating pin) is an industrial standard part widely used in mechanical connection and positioning scenarios. This type of product has clear characteristics in structural design, material selection, and functional positioning. As a professional hardware fastener manufacturer, we provide high-strength carbon steel galvanized flat head cylindrical pin with hole to solve the problems related to mechanical positioning, hinge connection, and heavy equipment assembly design, and meet the stringent requirements of global industrial customers for precision and reliability.

1. Product core introduction: Materials and processes

Select high-quality carbon steel through quenching and tempering heat treatment to make its hardness reach HRC 28-463, and the surface galvanizing treatment makes it have excellent rust and corrosion resistance.

Product Picture

 

Specification range: diameter M3-M10, support length customization, through hole adapts to standard cotter pins.

Application scenarios: Cylindrical locating pins are widely used in aluminum formwork connections, engineering machinery articulation, automobile chassis, bridge steel structures, and other fields that require high shear and impact resistance.

2. Core advantages of the product

Excellent load-bearing performance: interference fit design, fixed in the reamed hole by slight interference, strong shear resistance when transmitting power, so as to achieve excellent variable load and impact resistance.

The 10.9 grade high-strength version can be selected with carbon steel quenched + tempered, which is suitable for dynamic load scenarios such as bridges and heavy machinery.

Accuracy and reliability: good centering, positioning accuracy of ±0.01mm, ensuring assembly consistency; flat head design prevents axial displacement, and the through hole can be inserted with a cotter pin to achieve double locking; compared with elastic cylindrical pins, it has stronger rigidity and is more suitable for high-precision positioning scenarios.

Long-term protection: The galvanized layer provides a uniform anti-corrosion barrier, resistant to salt spray for more than 500 hours, and is suitable for humid environments such as outdoor building aluminum formwork and ship equipment.
