BFKK Ferrule Crimping Tool Kit AWG 24-10 21 Sizes

Wire Ferrules Kit Contents

The kit supplies 21 sizes of tinned-copper ferrules with nylon insulating sleeves covering the AWG 24-10 range. A hexagonal crimping tool with adjustable force and a quick-release lever is included, all packed in a storage box. It is intended for professional electricians and DIY enthusiasts who need a ready-to-use assortment for terminating stranded wire. The nylon sleeves provide insulation and flame-retardant properties for safe, reliable connections.

Capacity and Crimp Range

The ferrules accommodate conductors from AWG 24 up to AWG 10, giving headroom for most common control-panel and appliance wiring tasks. The ratchet mechanism ensures consistent compression across the full range, while the adjustable force lets the user match crimp pressure to each terminal size. The kit runs out at AWG 10; larger gauge conductors require different ferrules and a tool with larger dies. The 21-piece assortment covers the stated range but does not extend beyond it.

Hexagonal Crimping Limits

Hexagonal crimping produces a six-sided profile that suits round contact surfaces on terminal blocks and spring-clamp connectors. The method is stronger for small terminals than indent crimping, yet the dies are fixed to the AWG 24-10 window. The tool cannot accept square or trapezoidal die sets, so it cannot be adapted for other ferrule profiles or larger wire sizes. The quick-release lever prevents stuck terminals but does not change the fundamental capacity of the die set.
