The Essential Guide to 5/8 Clevis Pins: Dimensions, Materials, and Sourcing from China’s Reliable Foundry
Meta Title: 5/8 Clevis Pin | High-Quality Clevis Pins for Agriculture, Construction & OEM – TJJ Trade
If you are sourcing a 5 8 clevis pin for heavy‑duty linkages, you need a component that meets exact dimensional tolerances, material strength, and surface finish. A 5/8″ clevis pin (0.625″ diameter) is commonly used in tractor hitches, hydraulic cylinders, agricultural implements, and construction equipment. At Shijiazhuang TJJ Trade, we manufacture these pins with precision casting and machining, backed by over 20 years of foundry experience. This guide covers everything a sourcing manager needs to know: sizes, grades, customization options, lead times, and how to partner with a factory that delivers consistent quality.
Industry Pain Points When Sourcing 5/8 Clevis Pins
- Inconsistent dimensions: Pins that are out of tolerance cause fitment issues and safety risks in critical linkages.
- Low-grade materials: Many suppliers use 1008/1010 steel that wears quickly; buyers need 1045, 4140, or stainless for corrosion resistance.
- Surface defects: Burrs, rough finishes, or poor cotter‑hole alignment lead to rejection during assembly.
- Unreliable lead times: Delays in pin supply can halt entire production lines.
- Lack of customization: Off‑the‑shelf pins rarely meet specific hole sizes, chamfer angles, or coating requirements.
These challenges cost importers time, money, and reputation. The solution lies in partnering with a foundry that controls the entire process – from raw material to final inspection.
Our Solution: Precision‑Engineered 5/8 Clevis Pins
At Shijiazhuang TJJ Trade, we produce 5/8 clevis pins using investment casting or cold forging (depending on quantity and application). Every pin is manufactured to ANSI/ASME B18.8.2 standards (or custom specs) and passes through:
- Chemical analysis & tensile testing per batch
- Dimensional inspection with optical comparators
- 60‑second hardness test (Rockwell) for heat‑treated pins
- 100% visual inspection for burrs and surface defects
We offer a full range of 5/8 clevis pin styles: plain, with cotter hole, with drilled head, and custom designs. Below is a typical specification table.
| Parameter | Value |
|---|---|
| Diameter | 5/8″ (0.625″) ±0.005″ |
| Length Range | 1″ to 8″ (custom up to 12″) |
| Materials | Carbon Steel (1045, 1018), Alloy Steel (4140), Stainless (304, 316), Brass, 12L14 |
| Heat Treatment | Quench & temper (HRC 25–35), induction hardening on request |
| Surface Finish | Plain, black oxide, zinc‑plated, hot‑dip galvanized, Dacromet |
| Cotter Hole | 1/8″ or 3/16″ diameter, located per customer drawing |
| Standards | ANSI B18.8.2, ISO 2340, ASME, or custom |
*All dimensions and tolerances are indicative. Please refer to actual order confirmation for exact parameters.
Where is a 5/8 Clevis Pin Used?
The 5/8 clevis pin is a versatile component found in many industries:
- Agriculture: Tractor top links, implement hitches, baler pins, mower linkages
- Construction: Excavator bucket cylinders, crane sheave pins, scaffold connectors
- Automotive: Truck fifth wheel hitches, suspension links, steering components
- Marine: Winch mounts, rudder assemblies, dock hardware
- Industrial machinery: Conveyor belt joints, press brake tooling, hydraulic cylinder ends
Each application demands specific material and finish. Our engineers assist you in selecting the optimal grade – for example, 4140 alloy for high‑stress hydraulic applications, or 316 stainless for coastal marine environments.
OEM/ODM Customization for Your Exact Needs
We treat every 5/8 clevis pin order as a partnership. Our OEM/ODM services include:
- Non‑standard lengths & diameters – from 0.500″ up to 1.500″
- Special hole configurations – multiple cross‑holes, threaded ends, keyways
- Custom chamfers or radius ends to facilitate assembly
- Branding & packaging – laser engraving, poly bags with barcode, bulk cartons
We also support design‑for‑manufacturability: if you have a drawing but are unsure of tolerances, our team can suggest cost‑effective alternatives without sacrificing quality.
Example: A US agricultural OEM needed 10,000 pcs of 5/8 clevis pin with a specific offset cross‑hole for quick‑attach couplers. After reviewing the drawing, we suggested using 1045 steel with induction hardening on the bearing surface – reducing total cost by 12% while exceeding the required fatigue life.
Quality Assurance & Compliance
Quality is not a tagline at TJJ – it is embedded in our foundry processes. Our facility is ISO 9001:2015 compliant (certificate available on request), and we maintain strict traceability from melt to finished product.
Each batch of 5/8 clevis pins ships with:
- Mill certificate for raw material
- Inspection report (dimensions, hardness, surface finish)
- RoHS & REACH declarations for coatings (zinc, Dacromet, etc.)
- Photographic record of sample approval
For customers requiring third‑party inspection, we gladly coordinate with SGS, TÜV, or your designated inspector at our facility.
*Certifications are subject to verification before order. Contact our sales team for specific compliance requirements.
