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
In construction and infrastructure projects, release pins made from
carbon steel grades 4.8, 8.8, and 12.9 are essential for providing
robust fastening solutions. These grades of carbon steel are known
for their high tensile strength, resistance to deformation, and
ability to perform under heavy loads, making them ideal for
demanding applications. The pins are available in a variety of
sizes ranging from M3 to M18 and also in common inch measurements
such as 7/16”, 1/2”, and 9/16”, providing flexibility for different
project needs.
In construction, release pins are used in temporary scaffolding,
formwork, and heavy equipment. These pins ensure that components
can be securely held in place and released quickly when necessary,
improving the efficiency of construction processes. For instance,
when assembling large steel structures or concrete molds, these
pins allow for easy and safe removal of components, reducing labor
costs and preventing injuries associated with manual handling.
In large infrastructure projects such as bridges, tunnels, and
highways, carbon steel release pins are used to hold critical parts
together during assembly. Their high tensile strength ensures that
they can withstand the stress and weight of heavy equipment and
materials. Additionally, carbon steel pins are cost-effective and
versatile, making them a popular choice for large-scale
infrastructure applications.
The durability of carbon steel release pins also ensures that they
can perform reliably throughout the duration of a construction
project, even in environments exposed to harsh weather conditions.
For projects that require frequent assembly and disassembly, the
corrosion resistance of carbon steel, combined with its
cost-effectiveness, makes these release pins an essential component
in construction and infrastructure sectors.
