We specialize in high-precision custom manufacturing of stainless steel handles (T-type, L-type) and ball lock pins. All products are CNC-machined from 304/316/17-4PH stainless steel with optional surface treatments (passivation, electropolishing, sandblasting). Full customization available for dimensions, logos, and special requirements.
We specialize in manufacturing customized stainless steel quick release pins (ball lock pins) for global industries. Our products support full customization in dimensions, handles, materials, and surface treatments. From prototype to mass production, we ensure precision tolerance (up to ±0.005mm) and rigorous quality control.
These threaded lift pins feature an integrated self-locking mechanism that prevents unintended loosening under vibration or load changes. The precision threads provide controlled lifting and lowering motion, while the locking design ensures maintained position until manually adjusted. Ideal for applications requiring stable and repeatable height adjustment.
These versatile push button quick release pins are available with or without safety lanyards. The lanyard option prevents accidental loss in critical applications, while the standard version offers maximum flexibility. Both variants feature the same reliable one-handed operation - press the button to retract the balls for instant release, and release to lock securely.
Push button quick release pins enable rapid, one-handed operation without tools. Simply press the button to retract the spring-loaded balls for easy insertion or removal, then release to lock securely in place. These versatile pins are manufactured with precision tolerances and durable materials for reliable performance in countless applications.
Push button quick release pins feature a spring-loaded mechanism that allows for effortless insertion and removal with a simple press of the button. These pins are ideal for applications requiring frequent and rapid disassembly. Made from durable materials like stainless steel or carbon steel, they offer reliable performance in industrial, automotive, and aerospace settings. The ergonomic button design ensures smooth operation even with gloves.
Ball lock pins (also known as quick release pins) are engineered with spring-loaded balls that retract upon insertion and expand to lock securely into place. These pins provide instant, tool-free fastening and release, making them ideal for applications requiring frequent disassembly. Manufactured from materials like stainless steel, carbon steel, or aluminum, they offer high strength, corrosion resistance, and durability. Available in various handle styles (T-handle, L-handle, button, ring) and sizes, ball lock pins are widely used in aerospace, automotive, industrial machinery, and military equipment.
Our high precision quick release pins are engineered for applications demanding tight tolerances (as low as ±0.005mm) and repeatable accuracy. Made from premium stainless steel or alloy steel, these pins feature a spring-loaded ball mechanism for instant tool-free operation. Customization includes diameters (1mm to 30mm), grip lengths (5mm to 300mm), handle types (T-handle, L-handle, button, ring), and surface treatments (passivation, plating, polishing). Ideal for aerospace, medical devices, and precision instrumentation.
Engineered for heavy-duty use, our T-handle quick release pins combine the instant locking mechanism of spring-loaded balls with an ergonomic T-grip for enhanced leverage. The oversized T-handle allows for comfortable operation even with gloves, while the stainless steel construction ensures corrosion resistance in harsh environments. Ideal for applications requiring frequent, high-force adjustments.
Crafted from premium 304 stainless steel, these quick release pins deliver exceptional corrosion resistance and mechanical strength for demanding environments. The spring-loaded ball mechanism enables tool-free, one-handed operation—press the button to retract the balls for insertion/removal, release to lock securely. Precision-machined to tolerances within ±0.01mm, they ensure repeatable accuracy in high-vibration applications. The natural silver finish offers a clean, hygienic surface ideal for food processing, pharmaceuticals, and marine hardware.
Manufactured from grade 304 stainless steel with a natural silver finish, these quick release pins offer excellent corrosion resistance and durability. The spring-loaded ball mechanism ensures secure locking and instant release with smooth push-button operation. Precision machined to tight tolerances for reliable performance in industrial, marine, and food processing applications.
