SN58B Crimping Pliers — Ratcheting, Interchangeable 6Jaw Set for XH2.54 / 2.54 / 2.8 / 4.8 / 6.3 NonInsulated and Ferrule Terminals Why this tool matters One versatile tool replaces multiple singlesize crimpers. The SN58B with six interchangeable jaws lets you handle common connector pitches and terminal types without swapping tools. Ratcheting mechanism delivers consistent, repeatable crimps by completing the full crimp cycle and releasing only when the crimp is finished — reducing wasted terminals and rework. Designed for noninsulated terminals and ferrules used in electronics, appliances, and wiring assemblies; it improves productivity and crimp quality for hobbyists and professionals. Key features and benefits Model: SN58B (6jaw set) — includes six interchangeable jaws to match connector sizes listed below. Compatibility: XH2.54, 2.54, 2.8, 4.8, 6.3 — matches common pin header pitches and blade/spade terminal widths. Terminal types: Noninsulated terminals and ferrule terminals — suitable for standard noninsulated crimps and ferrule end crimps. Ratcheting action: Ensures a complete and uniform crimp cycle for reliable electrical and mechanical connections. Interchangeable jaws: Quickchange jaw system lets you switch between terminal sizes without a separate tool for each size. Ease of use: Designed for consistent alignment of terminal and conductor for accurate crimps and reduced terminal damage. Performance and applications Provides repeatable crimps for consistent electrical contact and improved strain relief. Suited for assembly tasks that require changing terminal sizes frequently — ideal for bench work and smallbatch production. Typical use cases Electronics assembly and prototyping: Crimping JST XH and 2.54 mm pitch connector pins and housings for custom cable assemblies, singleboard computer projects, and sensor wiring. Appliance and equipment wiring: Crimping 2.8 mm, 4.8 mm, and 6.3 mm noninsulated spade terminals for switches, relays, and automotivestyle connectors. Control panels and industrial wiring: Applying ferrules to stranded wire for secure terminal block and screw terminal connections. What you get SN58B ratcheting crimping pliers with a 6jaw interchangeable set matched to the sizes listed in the product title. Exact jaw set corresponds to XH2.54 / 2.54 / 2.8 / 4.8 / 6.3 compatibility for noninsulated and ferrule terminals. Notes Use with the terminal types and sizes specified. Check connector and terminal dimensions before crimping to ensure compatibility with the included jaws.
