Product Description
Product Overview
This product is a Type A fillet square key pin, manufactured in strict accordance with the GB/T 1096 Grade A standard. Made of 304 stainless steel, it has excellent rust and corrosion resistance. Its unique fillet structure can effectively avoid stress concentration and improve load-bearing strength, making it a standard basic part for connecting shafts and rotating parts (such as gears and pulleys) and transmitting torque.
Core Advantages
-
Excellent Rust and Corrosion Resistance: 304 stainless steel material, suitable for humid, chemical medium and other environments, with a long service life.
-
High Reliability of Fillet Structure: Both ends of the key body adopt fillet design, which effectively disperses stress, avoids local cracking of the keyway, and improves connection safety.
-
Standard Precision and Convenient Installation: Grade A precision, accurate size, high matching degree with the keyway, convenient installation, and ensuring stable transmission.
-
Wide Applicability, Economy and Durability: It combines the corrosion resistance of stainless steel and the moderate strength of Grade 4.8, meeting various working conditions with high comprehensive cost performance.

Warm Tips
-
Before installation, please ensure that the size and precision of the keyways of the shaft and hub match this product, avoiding over-tight or over-loose assembly which may affect the use effect.
-
It is recommended to apply an appropriate amount of grease on the mating surface of the key side during installation, which can prevent fretting corrosion and facilitate subsequent disassembly and maintenance.
