Where to use it
The heavy-duty hex crimper is for fitting large lugs to battery cables, inverter leads, welding leads and heavy-duty wiring in automotive, marine, solar and industrial work.
A proper hex crimp gives a solid, low-resistance connection that won't work loose.
A heavy-duty hex crimping tool is designed to crimp large cable lugs and terminals onto heavy-gauge cables ranging from 10mm² to 120mm². It’s ideal for high-current electrical systems such as solar battery banks, inverter wiring, and industrial power setups.
A hex crimp refers to the hexagonal shape formed around the lug during crimping. This shape delivers even compression around the cable, ensuring maximum electrical conductivity and mechanical strength for long-lasting, low-resistance connections.
Yes. Heavy-duty hex crimpers are typically suitable for both copper and aluminium lugs, though copper or tinned copper lugs are more common in solar and automotive applications.
Select the correct die size for your cable, insert the lug and stripped wire, and compress the handles until the die closes completely. A proper crimp should feel firm and have a uniform hex shape without visible gaps.
Yes. The tool is portable and manually operated, making it perfect for on-site use in solar, marine, or off-grid installations. Its heavy-duty steel construction ensures durability under demanding conditions.
Keep the dies clean, lightly oil the moving joints, and store the tool in its case to prevent rust or damage. Regular maintenance ensures smooth action, accurate crimps, and extends the lifespan of the tool.
