304 Stainless Steel Clevis Pins
with Cotter Pin | GB882 Flat Head Hole Type
DISLAB Precision — Precision-engineered fasteners for secure, removable mechanical connections.
Our 304 stainless steel clevis pins (flat head, hole type, GB 882 standard) are precision‑engineered fasteners designed for secure, removable mechanical connections. Manufactured from durable 304 stainless steel, these pins feature a flat head and a cross‑drilled hole for use with a matching split cotter pin, ensuring a vibration‑resistant lock that prevents accidental disengagement. Available in a wide range of diameters (M3 to M20) and lengths (8mm to 150mm), they provide reliable performance in applications requiring quick assembly, disassembly, and maintenance. The included split pin eliminates the need for tools during installation, making them ideal for agricultural machinery, automotive parts, lifting equipment, and general industrial assemblies.
Key Specifications & Technical Data
All clevis pins conform to GB882 standard, available in polished 304 stainless steel, including matching split cotter pins. The dimensional range covers most industrial requirements, and custom OEM/ODM lengths are supported.

Product Advantages
🔩 304 Stainless Steel Construction
Provides exceptional corrosion resistance, ideal for outdoor, humid, or mildly corrosive environments. Offers high tensile strength and long service life.
🔒 Secure Locking System
Cross-drilled hole plus split cotter pin creates a vibration-proof lock that prevents the pin from backing out under load — eliminates accidental disassembly.
⚙️ Tool‑Free Installation
No specialized tools required. Insert pin, then cotter pin, and bend the legs to secure. Drastically speeds up maintenance and repair work.
📏 Precision Machining & Wide Range
Tight tolerances ensure smooth fit. Over 200 standard configurations, from small hobby builds to large industrial machinery.
Design & Assembly Details
The flat head provides a flush, clean appearance and prevents the pin from pulling through the assembly. Each clevis pin comes with a matching split cotter pin, allowing instant locking without extra tools. High precision shoulder alignment ensures consistent fitting in clevis yokes and linkages, making them the preferred choice for dynamic connections in agriculture, automotive and heavy machinery.
Our 304 stainless steel variants guarantee rust resistance and retain mechanical strength under continuous vibration. For additional safety, the split pin legs can be bent back to secure the assembly, yet removal remains simple for maintenance cycles. Shown on the right is the actual flat head clevis pin with split pin configuration — a robust fastening solution that meets global standards.
Applications — Engineered for Reliability
🌾 Agricultural Machinery
Connecting linkages, control arms on tractors, harvesters, and farm equipment. Stainless steel resists moisture, fertilizers, pesticides; cotter pin prevents loosening from vibration.
🚜 Automotive & Trailer Components
Securing trailer hitches, suspension parts, brake linkages, convertible top mechanisms. Corrosion‑resistant finish withstands road salt, and removable design eases service.
🏗️ Lifting & Material Handling
Connecting chains, hooks, shackles on cranes, hoists, hand trucks. High tensile strength and secondary safety lock prevent catastrophic failure.
🛠️ General Industrial & DIY Projects
Workbenches, gates, hinges, robotics, custom machinery. Tool‑free design for quick assembly and rust‑free outdoor performance.

Real Customer Case
📌 European Agricultural Equipment Manufacturer – Bulk Order 50,000 pcs
A leading Italian agricultural machinery manufacturer ordered 50,000 pieces of 304 stainless steel clevis pins (M6, M8, M10, lengths 20‑50mm) for vineyard tractor linkages. DISLAB Precision delivered pre‑packaged sets with matching cotter pins, material test reports, and 100% dimensional inspection. The customer reported zero assembly issues, excellent vibration test performance, and the new tractor line launched on schedule. Since then they have become a repeat partner for fastener solutions.
Why choose us? Backed by 300+ qualified partner facilities, over 50 million pieces monthly capacity, 40+ engineering experts, and strict quality checks from material grade to surface finish. We support OEM/ODM custom diameters, lengths, 316 stainless steel, and custom packaging.
Frequently Asked Questions
❓ Clevis pin vs regular bolt?
A clevis pin is designed for quick removable connections with a split cotter pin, tool‑free assembly/disassembly — ideal for maintenance‑heavy applications.
🌊 Suitable for marine use?
304 stainless steel offers good resistance, but for continuous saltwater immersion we recommend 316 stainless steel clevis pins.
📏 How to select correct length?
Pin length = combined thickness of parts + clevis yoke thickness, ensuring the hole is fully exposed for cotter pin insertion.
♻️ Reusing cotter pins?
For safety‑critical applications, always use a new cotter pin each installation. Reusing bent pins may compromise locking.
🛠️ Custom clevis pins possible?
Yes, full OEM/ODM: custom diameters, lengths, 316 stainless steel, carbon steel, special head styles.
