Custom High Strength Stainless Steel Ring Safety Pull Pins Quick Release Bolts Retractable Locating Spring Locking Pin
Product Introduction
High-Quality Materials: Stainless steel, steel, plastic, brass, and more ensure durability and reliability.
Precision Components: Ideal for applications requiring precise positioning and clamping.
Customizable Sizes: Available in M3-M24 or customized sizes for diverse needs.
Fast Delivery: Expect delivery times ranging from 3 to 25 days.
Wide Adaptability: Suitable for various types like press-in, threaded, ball-end, and cylindrical.
Various models, suitable for diverse industrial scenarios To meet the needs of different equipment and working conditions, we offer a rich product range, covering various installation methods and material options:
Cylindrical Retractable Spring Pin: A smooth cylindrical shell without threads, which can be directly pressed into the installation hole, suitable for workpieces and fixtures requiring interference fit. Made of stainless steel, it is wear-resistant and rust-proof, maintaining stable elasticity and positioning accuracy even under high-frequency extension and retraction actions.
Threaded Spring Indexing Pin: With external threads, it can be quickly locked in place through a nut, making disassembly and maintenance more convenient. Widely used in equipment indexing plates, fixtures, etc., where the positioning position needs to be frequently adjusted. Some models feature a brass shell combined with a stainless steel ball head, balancing conductivity and wear resistance, suitable for special usage requirements of electronic equipment.
Engineering plastic model Spring Loaded Retractable Pins: Using a chemically resistant engineering plastic shell and ceramic/nylon balls, it is lightweight and has good insulation properties, suitable for industries such as food, medicine, and electronics that are sensitive to metal contamination.
All products feature high-hardness stainless steel balls, combined with precisely machined springs, with smooth extension without jamming, and repeat positioning accuracy of ±0.02mm, ensuring precise and reliable positioning every time.

Full-cycle service, safeguarding your project YH FASTENER has always adhered to the service policy of "quality first, customer satisfaction, continuous improvement, and striving for excellence". It has established a full-cycle, one-stop after-sales service system covering pre-sale, in-sale, and post-sale stages, providing rapid response, efficient solutions, and professional and caring services to ensure comprehensive protection for customers.
In the pre-sale stage, we offer free technical consultation, scheme design, drawing optimization, sample provision, and price calculation services. The technical team provides one-on-one communication and makes precise recommendations for suitable Retractable Locking Pin models or optimizes and customizes the solution based on the customer's equipment condition, load requirements, and installation space, helping customers reduce costs, improve efficiency, and avoid product selection and design issues in advance.
In the in-sale stage, we establish a real-time order tracking mechanism, and the business team and production team work in tandem, regularly providing customers with production progress, inspection status, and logistics arrangements, allowing customers to fully grasp the order status throughout the process. For changes in requirements, process adjustments during the production process, we respond quickly and coordinate flexibly to ensure the smooth progress and timely delivery of the order.
In the post-sale stage, we implement a 7×24-hour rapid response mechanism. Customer inquiries, feedback, and complaints are responded to within 24 hours. We provide services such as unconditional return and replacement of quality issues, rapid re-delivery, and technical guidance. For non-standard customized products, we continuously provide long-term technical support for optimization and secondary customization. We have also established a complete customer file management system to record customer orders, product usage, and after-sales feedback, and conduct regular customer follow-ups to understand product usage and potential needs, proactively providing technical optimization and product upgrade suggestions, achieving long-term companion service.
