Punch set PRYOR Dot Stress

Punch set PRYOR dotstress

Dot stress punch sets A-Z and 0-9 available in 3.0 to 8.0 mm character size


Marking stamps “dot stress” introduce even lower stress levels than the punch “low stress” and enhance fatigue properties. Punches “dot stress” produce a character with similar rounded nose formation to low stress with the added benefit of impressing the character in a dot formation.


Dot stress marking stamps are used especially in the oil, gas and aircraft industry but also for power plants and similar applications. Instead of the sharp faced characters, these punches are manufactured with a radius engraving to reduce the stress levels. Please see the difference on the following illustration.

Our steel stamps are manufactured of high quality Chromium tool steel. All punches are hardened precisely, giving a hardness of 58-62 R.C. at the character end and 32-40 R.C. at the striking end. Please note, that the hardness of the component should not exceed 40 R.C. All sets are delivered in a strong plastic box with separate compartments for each stamp, to allow rapid selection. The production of these stamps is certificated after ISO 9001:2000. For special security requirements there is a special security holder available. Marking stamps of the series “dot stress“ are available as single punch as well as in sets of A-Z and 0-9 in different sizes. All standard stamps are nickel-plated and protected therefore against rust. Please, note that the size of the stamps must be measured on top at the sharp faced characters end.
