VÖLKEL Hexagon Die Nut DIN 382 HSS – BSF

VÖLKEL Hexagon Die Nut DIN 382 HSS – BSF

When you need fast, reliable external thread repair in tight spaces, this hexagon die nut is the right choice. You drive it with a standard ring or open-end spanner, so you can rethread bolts, studs and rods even where a die stock won’t fit. Made from durable HSS, it delivers clean, repeatable results across everyday workshop and maintenance tasks. For a quick demo, watch our how-to video.

Applications & Benefits

  • Rethreading and thread repair for damaged external threads (bolts, studs, rods)
  • Hex body for use with a spanner—ideal in confined or awkward locations
  • HSS construction for toughness and reduced chipping
  • Efficient chip spaces between cutting edges for smooth swarf evacuation
  • BSF thread profile to match British Standard Fine fasteners

See it in action: YouTube tutorial.

Step-by-Step Guide

  1. Clean & lubricate: remove dirt and rust; apply cutting oil or paste.
  2. Align square: start the die nut straight on the damaged thread to avoid cross-threading.
  3. Drive with a spanner: turn evenly; don’t force.
  4. Break chips: advance 1–2 turns, back off slightly to clear swarf; re-lubricate as needed.
  5. Finish & check: back off, wipe clean and test with a matching BSF nut or gauge.

FAQ

Can I use it without a die holder?
Yes—drive it directly with a ring or open-end spanner on the hex body.

Will it cut a new thread?
It’s primarily for rethreading/repair. For cutting new threads from scratch, use a round adjustable die in a die stock.

What lubricant should I use?
Use quality cutting oil or paste appropriate for the base material to improve finish and tool life.

How do I avoid cross-threading?
Start square, use gentle pressure, and feel for proper lead engagement. If it binds, back off and realign.

Is HSS right for general maintenance?
Yes—HSS offers good toughness and reduced brittleness, making it a solid choice for day-to-day repair work.
