⚡ At a Glance
- • Thread Coverage: Includes metric, imperial (G series) and a selection of US sizes plus 55° and 60° profiles
- • Best for: Machinists, workshop technicians and DIYers who need fast thread identification and tool setup
- • Not ideal for: Applications requiring certified metrology traceability or threads outside the listed sizes
Stainless steel blades fold into a compact set with a lock-up device for stable readings. Useful for pitch identification and checking thread cutting tool angles on a lathe.
Quick and reliable pitch identification – with 55° and 60° thread blades
Separate blades cut to 55° and 60° profiles let a gauge tooth seat into the thread form, showing a match by visual fit. Metric, imperial and US blades cover a wide range of common pitches and gauges.
Match threads rapidly without trial-and-error so you can select taps, dies or cutting tools with confidence. Saves time when sorting fasteners or preparing a lathe setup.
Durable, workshop-ready construction – with stainless steel blades and wire-drawn finish
Blades are made from stainless steel with a wire drawing surface treatment, reducing surface corrosion and wear during repeated use. Folded storage keeps edges protected when not in use.
Long-lasting blades resist rust and handle everyday workshop conditions, so measurements remain reliable over repeated jobs. Minimal maintenance required to keep the set serviceable.
Portable and organised – thanks to compact folding design and included case
Folding blades lock into position for safe checking and the set stores in a small case that keeps each blade accessible. A lock-up device secures a selected blade for hands-free comparison.
Easy to slip into a tool roll or drawer and carry between jobs, with reduced risk of losing blades. Quick access speeds up inspection and tool setup at the bench or on-site.
