Release Pin Carbon Steel Grade 4.8 8.8 12.9 7/16'' 1/2'' 9/16'' Used in Construction and Infrastructure

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.
