1/2 Clevis: Durable Cast Iron Hardware for Ornamental Fencing & Gates
Looking for a reliable 1/2 clevis to secure your ornamental iron fence or gate hinges? As a B2B buyer, you need a component that offers consistent dimensions, high tensile strength, and corrosion resistance – without supply delays. At SHIJIAZHUANG TJJ TRADE CO.,LTD., our 1/2 clevis is precision cast from premium malleable iron, meeting ASTM A47 standards. Backed by 20+ years of founding experience and serving markets across the USA, Europe, and Africa, we provide OEM/ODM customization, competitive MOQs, and 30-day lead times. Read on for full specifications, certifications, and why import managers trust TJJ.
Why Import Managers Struggle with Standard Clevis Hardware
In the ornamental iron and gate hardware industry, a 1/2 clevis might seem like a simple part, but poor-quality clevises cause costly issues:
- Inconsistent pin hole diameters – leading to hard hinge assembly or loose fit.
- Brittle material prone to cracking under heavy gate loads.
- Rust and surface defects that require extra finishing or cause customer complaints.
- Long lead times from overseas suppliers and poor communication on order status.
These problems waste time, increase rework, and damage your brand reputation. That's why more sourcing agents and wholesalers are turning to a foundry that combines quality control, flexible customization, and reliable logistics.

Our 1/2 clevis is designed for heavy-duty ornamental gates, patio fences, and architectural ironwork. Manufactured in our ISO 9001 certified foundry (est. 2004) in Hebei, China, each piece undergoes strict dimensional and strength checks.

What Our Buyers Say About Our 1/2 Clevis
Operations Manager, FenceGates USA (Texas)
“We import clevises for our gate line. TJJ’s 1/2 clevis has consistent threads and the powder coat holds up well in our humid climate. No more customer callbacks about stuck pins. Great value.”
Sourcing Agent, Ironworks Mexico (Monterrey)
“Switched to TJJ in 2024. Their 1/2 clevis meets ASTM specs and the lead time is consistently 30 days. Plus they helped us customize the clevis with a longer pin for heavy gates.”
Product Developer, HomeScape Hardware (California)
“The factory is ISO certified and it shows. Our 1/2 clevis samples had perfect dimensions – no rework needed. We now use TJJ for multiple ornamental iron items.”

Where to Use a 1/2 Clevis in Ornamental Ironwork
The 1/2 clevis is commonly used as a connecting component for:
- Gate hinges (attaching leaf to post)
- Drop rods and latch mechanisms
- Adjustable railing brackets
- Decorative tie rods in wrought iron fences
Our clevis works with standard 1/2-inch pins and bolts, making it compatible with most North American gate hardware systems.
