P&N 52-Blade Thread Pitch Gauge — Metric & Whitworth
Part No: 268MW0052 | Barcode: 9311744436026 | Series: P&N Workshop Thread Gauges
The P&N 268MW0052 is a 52-blade combined metric and Whitworth thread-pitch gauge for identifying ISO metric (0.25–6.0mm) and BSW/Whitworth (4–62 TPI) threads in one pocket tool. Each carbon-steel blade is precision-milled and clearly stamped, so you can visually match a mystery thread without hunting through multiple gauges.

Key Features & Benefits
- Combined metric + Whitworth coverage — one tool covers both standards, which means no guessing whether a fastener is metric or imperial before you reach for the right gauge.
- 52 precision-milled blades — each leaf is stamped with its pitch or TPI, giving comprehensive coverage across both standards in the common workshop range.
- Carbon-steel construction — blades hold their tooth profile under repeated comparison against hardened thread surfaces.
- Centre clamping screw — lock an isolated blade out to probe internal threads or tapped blind holes where a full gauge body won’t fit.
- P&N workshop heritage — precision-milled teeth from an Australian tool brand with decades of cutting-tool experience.
When to Use the 268MW0052
Reach for the 268MW0052 when you’re diagnosing an unknown thread on a mixed-heritage workshop — modern metric parts alongside older British-spec machinery where Whitworth and BSW turn up regularly. For pure metric work a 24-blade metric gauge is lighter; for UNC/UNF-only work the 268UNC022 or 268UNF016 variants are more focused.
Pro Tip: When matching a thread, check two or three blades either side of your best guess — the correct pitch seats cleanly across the full length of the thread with no rocking, while a near-match will seat in the centre but rock at the ends. This is the single most reliable test for confirming pitch identification before cutting a matching thread.
