PRYOR Low Stress Steel Hand Stamps .

A range of high performance, low-cost precision hand stamps, ideal for applications which dictate that lower stress levels are introduced into the component being marked. This is usually a requirement for Aerospace, Nuclear, Oil and Gas installations, and some M.O.D. work.

2 Styles of Low-stress engraving available

  • Ministress - round-faced engraving which gives a continuous line character when marked.
  • Dotstress - for even greater reduced stress levels, a character with similar nose formation to Ministress but with the added benefit of impressing the character in dot formation.

All the stamps in this range are hardened and tempered to precise limits, nickel plated for rust protection thus giving maximum safety in use and long product life.
