E-type Snap Spring 304 Stainless Steel Carbon Steel M1.2-M15 Retaining Clip
The E-type snap spring is a compact retaining ring designed to hold components on shafts or in bores, preventing axial movement. Manufactured to standard GB/T896-1986, it delivers reliable dimensions and fit for mechanical assemblies, repairs, and DIY projects. Available in both carbon steel and 304 stainless steel, with blackening or natural colour finishes, these clips cover a wide size range from M1.2 to M15. Whether you need a single piece for a quick fix or a pack of 10 for stock, this versatile spring clip offers a practical fastening solution.
Features and Construction
The E-type snap spring is built from either carbon steel or 304 stainless steel, giving you a choice between high strength and corrosion resistance. The surface can be blackened for a dark, oil-resistant finish or left natural for a clean metallic look. Each spring is stamped and formed to precise dimensions per GB/T896-1986, ensuring consistent groove fit and holding force.
Material and Build
Carbon steel springs are heat-treated for hardness and used in dry, non-corrosive environments. 304 stainless steel springs resist rust and are suitable for outdoor, marine, or food-contact applications where moisture is present. Both materials provide the spring tension needed to lock into standard E-type grooves.
Size and Practical Fit
Springs are sized by the opposite side diameter in millimetres, from M1.2 (1.2mm) up to M15 (15mm). Each size corresponds to a specific groove diameter for a snug, stable fit. For example, an M4 spring fits a 4mm groove. Always measure your groove before ordering to ensure correct selection.
Uses and Placement
These snap springs are commonly used in bicycles, motors, gearboxes, pumps, and small appliances where a lightweight, low-profile retaining ring is needed. They are also popular in prototyping and repair workshops for fixing bearings, gears, and shafts.
Event or Professional Use
Mechanics and engineers use E-type snap springs for quick assembly and disassembly of rotating parts. Their simple design allows installation and removal with retaining ring pliers, saving time compared to circlips or nuts.
Everyday Home Use
DIY enthusiasts find these springs handy for repairing lawn mowers, tools, furniture, and exercise equipment. A few sizes in the toolbox cover most common household maintenance needs.
Benefits and Buying Value
Buying from a standardised range means each spring fits as expected, reducing trial and error. The choice of material and finish allows you to match the spring to the working environment without over-specifying.
Reuse and Low Maintenance
Provided the spring is not over-stretched or deformed, it can be removed and re-used multiple times. No lubrication or special care is needed beyond keeping the groove clean.
