High-Strength Clevis Pins and Clips – Reliable & Customizable for USA Buyers | Shijiazhuang TJJ Trade
Clevis pins and clips are essential mechanical fasteners that securely connect components in agricultural equipment, construction machinery, and marine rigging. As a USA import manager or sourcing agent, you need a supplier that offers consistent quality, tight tolerances, and fast lead times without the volatility of on‑again‑off‑again deliveries. At Shijiazhuang TJJ TRADE CO., LTD., our 20‑year‑old foundry combines full‑in‑house casting, precision machining, and surface finishing to deliver clevis pins and clips that meet your exact specifications — from OEM custom dimensions to standard stock sizes — backed by ISO‑compliant quality control and China's cost‑effective supply chain.
Why USA Importers Face Headaches with Clevis Pin Sourcing
The global hardware market is flooded with inconsistent quality, long lead times, and limited customization. Many Chinese factories either lack in‑house foundries (relying on subpar subcontractors) or cannot handle small to medium volumes without huge MOQs. For clevis pins and clips, dimensional accuracy and material grade are non‑negotiable — a 0.1 mm tolerance error can cause assembly failure under load. As a brand owner or wholesaler, you need a partner who offers:
- Consistent material quality – no hidden carbon content variation.
- Flexible MOQ – from 500 pieces for standard sizes to 5,000+ for custom parts.
- Short lead times – 15–25 days after order confirmation.
- Genuine OD/OEM support – markings, packaging, coating, and special tolerances.
Shijiazhuang TJJ solves these pain points by leveraging its in‑house foundry, 20+ years of export experience, and a dedicated quality team that inspects every batch before shipment.
Our Clevis Pins and Clips – Technical Advantages That Matter
Material & Strength
- Carbon steel (1018, 1045, 12L14 free‑cutting)
- Stainless steel (304, 316) – ideal for marine or food‑processing environments
- Alloy steel for high‑load applications
- Tensile strength up to 120,000 psi (heat‑treated optional)
Finishes & Coatings
- Plain (self‑coloured) – economical for indoor use
- Zinc plated (clear, yellow, blue) – salt spray 72+ hours
- Hot‑dip galvanized – for harsh outdoor environments
- Black oxide, Dacromet, or powder coat on request

All pins are manufactured with chamfered ends, smooth surface finish (Ra ≤ 1.6 µm), and are fully deburred. Our clevis clips (R‑clips, cotter pins, hairpins, lynch pins) are produced from spring steel or stainless wire with precise spring tension to prevent accidental release.

What Our Customers Say
Mike J. – Purchasing Manager, Midwest Tractor Parts (USA)
“We switched to TJJ for our clevis pins and clips after several quality issues with another supplier. Their tolerances are spot‑on – we had zero rejects on our first 20,000‑piece order. The MOQ flexibility also helped us test new sizes without a huge upfront commitment.”
Sarah L. – Owner, East Coast Marine Rigging
“We needed stainless steel clevis pins for our boat customers. TJJ’s 316 grade pins arrived with a beautiful passivated finish and passed our salt‑spray test easily. Communication throughout the custom order was excellent – we’ll definitely reorder.”
David R. – Sourcing Agent, BuildPro Equipment
“I’ve been sourcing hardware from China for 10 years. TJJ is one of the few factories that actually delivers on time and keeps product quality consistent. Their ability to do OEM packaging with our logo and add custom clips was a game‑changer for our brand.”
Tom A. – Plant Manager, Greenfield Agriculture
“We were skeptical about a new supplier, but the free samples of clevis pins and clips convinced us. The hardness and thread finish were superior to our previous supplier from India. Lead times have been within 20 days for three orders now – reliable.”
Jenna W. – VP of Supply Chain, ProRigging Inc.
“TJJ’s team helped us engineer a custom clevis pin with a smaller head profile for a tight‑clearance application. Rapid prototyping and quick approval. Highly recommend for OEM work.”
