Precision cast iron/zinc T-shaped fixture forged parts for
automotive and motorcycle wiring systems
Product Overview
Our precision cast iron and zinc T-shaped fixtures are engineered
to provide secure, long-lasting wiring harness retention in
automotive and motorcycle applications. Manufactured using advanced
gravity casting and forging processes, these components deliver
superior mechanical strength, corrosion resistance, and dimensional
stability for demanding electrical systems.
Key Features & Benefits

FAQ
1. Why choose metal clamps over plastic for wiring systems?
Superior Durability: Withstands engine heat (up to 200°C vs.
nylon’s 120°C limit)
Vibration Proof: 3x longer fatigue life than plastic in
high-frequency environments
EMI Protection: Zinc alloys shield sensitive signals (critical for
EV/ADAS systems)
2. How do I select between iron, zinc, or forged versions?
| Factor | Cast Iron (GG25) | Zinc Alloy (ZA-12) | Forged Hybrid |
|---|
| Best For | Heavy-duty truck harnesses | Lightweight motorcycle looms | High-stress EV battery cables |
| Cost | $$ | $ | $$$ |
| Weight Savings | Baseline | 35% lighter | 20% lighter vs. iron |
| Key Advantage | Extreme load capacity | EMI shielding | Combined strength/weight |
3. What certifications do your clamps hold?
Automotive: IATF 16949, LV214-2 (EV)
Motorcycle: JASO D611, BMW GS-90003
Global: REACH, RoHS, IMDS registered
4. Can you customize clamps for specific harness diameters?
Yes, we offer:
Adjustable jaws (5-25mm range)
Rubber-lined grooves (for 0.5mm tolerance grip)
Quick-release designs for serviceability
5. How do you ensure corrosion resistance?
Iron: Zinc-nickel electroplating + sealer (1,200hrs salt spray)
Zinc: Blue trivalent chromate (504hrs ASTM B117)
Special: Dacromet coating for coastal/off-road use
6. What’s your MOQ and lead time?
