Release Pin Carbon Steel Grade 4.8 8.8 M3 M4 M6 Used in Automotive
and Machinery Applications
Product Description:
What is a quick release pin?
Quick release pins, also known as ball lock pins, locking pins or
safety pins, have a wide range of applications. They are used for
securing, locking, connecting, adjusting and facilitating quick
position changes.
When paired with a receiver plate, these pins provide a reliable
and secure locking feature. The design ensures ease of use and
facilitates quick changeover and replacement of parts as needed.
Quick release pins are highly resistant to shear, corrosion and
wear. This makes them ideal for applications that require frequent,
quick, manual assembly and disassembly of products.
Quick release pins are fastening connectors for quick locking and
removal of workpieces, and can be used to quickly connect and hook
up components. Pressing the button on the handle can make the steel
ball on the head of the pin body retract and push the quick release
pin through the hole of the workpiece; when the button is released,
the steel ball pops out and the quick release pin can not be pulled
out from the hole.
The pin body diameter and clamping length are processed with high
precision, which is suitable for all kinds of high-precision
positioning and insertion. Can be customised according to
customer's requirements.
Quick Release Pin Head and Handle Styles
Quick release pins usually have a pin and a handle and come in a
variety of handle styles. As such, they can also be categorised by
head/handle type:
T-Handle Quick Release Pins, Ring Handle Quick Release Pins,
L-Handle Quick Release Pins, Push Button Handle Quick Release Pins,
Double Acting Quick Release Pins, Lifting Pins
T-Handle A wide range of handles featuring a T-shaped handle for a
firm grip and simple operation. Attached parts are easily released
by pulling and holding the handle.
L-Handle Quick-Release Pins A compromise between the ring handle
and T-Handle variants. The release mechanism has an L-shaped handle
on only one side of the pin. These are suitable for applications
where a firm grip is required but there are space constraints.
Applications
Release pins made from carbon steel grades 4.8, 8.8, and 12.9 offer
exceptional durability and strength, making them ideal for use in
the automotive and industrial equipment sectors. These grades of
carbon steel are known for their ability to withstand high levels
of stress and wear, ensuring reliability in demanding environments.
The sizes ranging from M3 to M18 provide versatility, making these
release pins suitable for various applications, from small parts in
automotive systems to larger components in industrial machinery.
In automotive manufacturing, release pins are crucial for
quick-release mechanisms and safety features, facilitating
efficient assembly and disassembly of parts. For example, they are
often used in suspension systems, brake assemblies, and door
mechanisms. Their high tensile strength ensures that they can
handle the forces exerted in these applications without
compromising performance.
Similarly, in industrial machinery, release pins play a critical
role in simplifying the maintenance of complex equipment. They
allow for easy assembly, disassembly, and part replacement,
reducing downtime and increasing operational efficiency. The high
strength of these carbon steel pins ensures that they remain
functional even under heavy-duty conditions, making them a go-to
choice for industries like construction, mining, and material
handling.
These pins are designed to meet the requirements of heavy-duty
environments where regular wear and tear can be a concern. The
material properties of carbon steel provide resistance to
corrosion, though additional coatings may be applied depending on
the specific environmental conditions. Overall, release pins made
from carbon steel grades 4.8, 8.8, and 12.9 are indispensable in
the automotive and industrial sectors due to their strength,
reliability, and versatility.
