The Hanlong HT-T51 Hexagonal Crimper is engineered for professional electrical work where precision, durability, and ease of use matter. Designed to handle copper and aluminum cable lugs, terminals, and conductors across a 6-120 mm² range, this tool pairs rugged construction with smart features to make crimping faster, cleaner, and safer—from panel installs to field upgrades.

• Hexagonal central crimp design provides consistent, high-torque compression every time, producing a secure, long-lasting connection that resists loosening and corrosion. This geometry optimizes contact area for both copper and aluminum conductors.
• Spring-loaded locking pin lets you rotate and select the desired crimp size quickly and smoothly, reducing setup time and increasing workflow efficiency on busy jobsites.
• Embossed gauge code on jaws gives immediate, at-a-glance size verification, helping you avoid under- or over-crimping and ensuring correct lug termination for every application.
• Lever-action with anti-slip grips minimizes hand fatigue while delivering precise control, even in tight spaces or when wearing gloves. The leverage design means you apply pressure efficiently, not exhaustively.
• Extended reach of 660 mm provides superior accessibility for hard-to-reach crimp points, from distribution panels to heavy-duty battery cables and motor leads.
• Heavy-duty construction with a 3.66 kg weight profile delivers robust performance for repetitive, high-torque crimps in demanding electrical and power applications.
• Versatile 6-120 mm² range supports a wide variety of lugs, terminals, and conductors, making the HT-T51 a reliable staple for electricians, industrial installers, and maintenance teams alike.

Who should use the HT-T51? Ideal for electricians, technicians, and installers tackling service entrances, panel upgrades, motor leads, battery cables, and other high-current connections that require consistent, code-compliant crimps on both copper and aluminum wiring. It’s particularly valuable in environments where speed, accuracy, and repetitive reliability are essential—from on-site industrial projects to controlled workshop tasks.

Why choose this hexagonal crimper over standard round-crimp tools? The unique hexagonal crimp geometry, combined with a gauge-guided jaw system and a user-friendly locking mechanism, delivers fewer failed crimps, faster setup, and superior durability under heavy use. The HT-T51 is built to maintain performance over time, even when working with demanding conductor sizes and challenging installation conditions.

Practical tips for best results: align the lug or terminal with the embossed gauge mark, rotate to the correct size using the locking pin, and apply steady, even pressure with the lever action. After crimping, inspect the connection for full compression and clean contact surfaces to ensure optimal conductivity and longevity.
