Sutton Die Nut — M16x1.5
Part No: M4411607 | Barcode: 9311963029900 | Brand: Sutton Tools
Sutton hexagonal die nut for restoring damaged or corroded external threads. Hex shape lets you turn it with a standard spanner — ideal for rust-bound bolts, studs and cylinder-head fasteners where a button die and stock would not fit. This M16x1.5 variant covers the Metric Fine (MF) thread standard — Fine-pitch ISO Metric — for restoring fine-pitch metric threads on automotive and hydraulic fasteners.

Key Features & Benefits
- Hexagonal body — turns with any standard open-ended or socket spanner — no die stock required, perfect for in-situ repair.
- Designed for rethreading — restores the existing thread profile rather than cutting fresh material — preserves fastener strength.
- Hardened cutting edges — cleans rust, paint and damaged crests from automotive, agricultural and engineering fasteners.
- Compact form — reaches studs and bolts in confined engine bays, frames and brackets where dies and stocks won’t go.
- Australian made — Sutton Tools, family-owned and manufacturing in Thomastown, Victoria since 1917.
When to Use This Die Nut
Reach for a die nut whenever you need to chase, clean or restore an existing external thread — automotive head studs, exhaust studs, rusted bolts after sand-blasting, painted-over thread crests. Don’t use it to cut a brand-new thread from scratch (that’s a button die’s job) — die nuts re-form the existing crests rather than removing material. This particular variant (M4411607) cuts a M16x1.5 thread.
Pro Tip: A die nut chases threads — it isn’t designed to cut fresh ones. If a fastener looks badly stripped or oversized, replace it rather than relying on a chased thread to hold full torque. For best results wire-brush loose rust off first, then run the die nut on with cutting oil applied generously.
