Introduction
In the fast-paced worlds of maritime rigging, aerospace maintenance, and industrial automation, efficiency is measured in seconds. Conventional nut-and-bolt assemblies often fall short when rapid adjustments are required. Enter the Ring Grip Quick Release Pin (also known as a Detent Pin)—a precision-engineered fastener designed for instant manual locking and tool-free operation.
I. The Science of the Dual-Ball Locking Mechanism
The reliability of the products series (and similar detent pins) stems from its spring-loaded mechanism.
Self-Locking Logic: Two stainless steel balls at the pin’s tip are pushed outward by an internal spring.
Installation: As the pin enters a hole, the balls retract; once through, they snap back out to create a secure mechanical stop.
Vibration Resistance: This design ensures the pin remains in place even under significant industrial vibration, making it ideal for moving machinery.
II. Material Science: Choosing for Your Environment
Selecting the right material is the difference between a long-lasting component and a structural failure.
| Material | Finish | Best Application |
| SUS316 Stainless | Plain | Marine Grade: Ultimate resistance to chloride and saltwater corrosion. Essential for yachts and offshore rigs. |
| SUS304 Stainless | Plain | Industrial/Food: Excellent hygiene and basic corrosion resistance for medical and food-processing equipment. |
| Carbon Steel | Zinc/Nickel Plated | Heavy Duty: High shear strength for indoor mechanical positioning and automotive jigs. |
III. Global Standards: Metric and Imperial Versatility
To support international engineering projects, these pins are manufactured to fit both Metric and US Standard (Imperial) hole sizes:
Metric Diameters: Standard stock from 3mm to 20mm.
Inch Equivalents: Precision sizing for 1/4″ (6.35mm), 3/8″ (9.5mm), and 1/2″ (12.7mm) applications.
Usable Lengths: Flexible sizing from 10mm up to 150mm to accommodate varying material thicknesses.
IV. Strategic Sourcing: The Sinobolt Advantage
Expert Insight: Given the current volatility in metal futures—specifically the fluctuating costs of Nickel and Chromium—securing stainless steel components at a stable price is a challenge for many procurement teams.
At Sinobolt, we leverage our dual expertise in metal futures and high-end manufacturing to help our clients manage cost risks. We offer:
