20 PCS Small Weld Tabs, Weld Tabs1-1/2 Height, 1" Wide, 4/21" Thick, Heavy Duty Brackets Weld On Tabs, Acid-Etched Steel Weld-On Tabs are Easier to Weld

📦【Precision Small Weld tabs - Designed for Tight Spaces】This product is a pack of 20 pcs weld tabs each with a 3/8" hole, 1-1/2" height, 1" width, and upgraded 4/21" thickness. The precision laser cutting 3/8" hole maintains exacting ±0.1mm tolerances, ensuring secure fastener placement even in high-vibration environments.

🚀【4/21" Thicker Advantage - Say Goodbye to 3/16" Weak Design】 Compared to the 3/16" thick used by most weld tabs on the market, our weld tabs enhanced 4/21" thick design. More importantly, we refuse to use "blackboards" and galvanized sheets that are not welding-friendly – these materials produce toxic gases and have poor adhesion when welding. Our Acid Washed Steel substrates are optimized for welding with a clean, uncoated surface that ensures strong welds.

🛡【High-Quality Acid Washed Steel - Double Guarantee of Strength and Durability】Made of high-grade acid washed steel substrate, after 650°C stress relief annealing treatment, the residual stress is reduced by 40%. Vacuum degassing technology strictly controls the hydrogen content below 2ppm, basically eliminating the risk of hydrogen-induced cracking. Each weld on tabs can withstand a shear load of 12kN, which is equivalent to the weight of a suspended motorcycle engine, and the hardness is controlled in the optimal range of HV130-150, which not only ensures strength but also facilitates welding processing.

🔧【Multi-Scenario - From Precision Instruments to Heavy Equipment】These weld on tabs are designed for a wide range of applications: frame reinforcement, iron mounting, mechanical accessories, buggy roll cages, trailer suspension systems, and more. The pickling finish provides 3 times longer rust protection than ordinary steel, making it particularly suitable for use in wet and harsh environments. Professional advice: Use with primer to obtain ultra-long protection effect for more than 10 years.
