Whitepaper Standard Engineering Specifications, Shear Strength Analysis, and Precision Fastening Systems
Clevis pins are unthreaded fast-release fasteners designed to absorb lateral shear forces while allowing dynamic rotational movement between connected components. Featuring a flat cylindrical head, a solid shank with a cross-drilled hole, and compatible retaining mechanisms (such as R-clips, cotter pins, or linch pins), these hardware assortments represent a critical structural link in modern mechanical assemblies.
As a leading wholesale clevis pin assortment manufacturer and supplier, Qingdao Rui De Tai Metal Products Co. Ltd manufactures high-tensile carbon steel, alloy steel, and marine-grade austenitic stainless steel clevis pins engineered strictly according to ISO 2341, DIN 1444, and ANSI B18.8.1 international standards.
Technical Distinction: Unlike standard hex bolts, clevis pins do not depend on torque tensioning. Instead, they operate as unthreaded hinge points engineered to endure high shear loading without dynamic structural fatigue.
To meet the extreme operational demands of marine, heavy construction, and automotive application scenarios, our comprehensive clevis pin assortments undergo rigorous surface treatment and precise metallurgical formulation:
| Material Specification | Yield Strength (MPa) | Tensile Strength (MPa) | Shear Resistance Rating | Standard Surface Finish | Recommended Environment |
|---|---|---|---|---|---|
| AISI 316 Stainless Steel | ≥ 290 | ≥ 620 | Extreme Shear / Cyclic Flex | Passivated / Electro-Polished | Offshore & Marine Sector |
| AISI 304 Stainless Steel | ≥ 245 | ≥ 580 | High Shear Load | Clean Passivated | Food Handling & Automotive |
| C45 Carbon Steel (Heat Treated) | ≥ 490 | ≥ 690 | Ultra-High Shear Tensile | Yellow / White Zinc Electroplated | Agricultural Machinery |
| 42CrMo Alloy Steel (Forged) | ≥ 785 | ≥ 980 | Heavy Duty Dynamic Load | Hot-Dip Galvanized (HDG) | Heavy Engineering & Port Cranes |
Qingdao Rui De Tai Metal Products Co. Ltd — Premier Chinese Rigging Hardware Manufacturer
Qingdao Rui De Tai Metal Products Co. Ltd is an established industrial enterprise specializing in the high-precision manufacturing of professional rigging products, clevis pin assortments, shackles, turnbuckles, load binders, wire rope clips, and marine hardware. Located in the coastal logistics hub of Qingdao, China, our modern industrial complex operates in close proximity to the Qingdao International Airport and major sea container terminals.
Equipped with advanced domestic drop-forging production lines, heat-treatment facilities, and rigorous automated inspection systems, our company combines senior industrial management with deep technical expertise. We serve global commercial distributors, equipment manufacturers, and infrastructure contractors across North America, Europe, Asia-Pacific, and the Middle East.
Beyond our standard catalog assortments, our technical team provides rapid OEM & ODM custom manufacturing according to technical drawings, physical samples, and custom mechanical specs provided by our global clients.
Since 2010, our manufacturing plants have adhered strictly to global quality control systems. Every batch of clevis pins and rigging hardware undergoes rigorous tensile breaking tests, dimensional calibration, magnetic particle flaw detection, and salt spray exposure tests under SGS testing frameworks.
Analyzing Supply Chain Integrity, Bulk B2B Procurement, and Heavy Hardware Optimization
Global original equipment manufacturers (OEMs) demand zero-defect fastener shipments. Our strategic factory placement near Qingdao Port ensures seamless sea freight shipping, low transit latency, and stable inventory replenishments worldwide.
We pack customized hardware kits featuring standardized metric (M3 to M24) and imperial (3/16" to 1") clevis pins with matching hairpins, cotter pins, and washers. Pre-sorted compartmental packaging streamlines assembly-line productivity.
With industries expanding into offshore wind energy, deep-sea marine transport, and chemical processing, our advanced hot-dip galvanizing and 316 passivation technologies prevent premature stress-corrosion cracking (SCC).
Our products serve robust commercial industrial networks across North America, South America, Europe, Africa, Asia-Pacific, and the Middle East.
Key Export Regions: Australia, Philippines, Marshall Islands, New Caledonia, French Polynesia, North America, Cuba, Nigeria, Egypt, Germany, Madagascar
