ABOUT THE SPEK M ANCHOR
The Spek M Anchor, also referred to as Spek type M, is one of the most widely used stockless anchors for ships in the maritime industry worldwide.
It's design is mainly the same as the regular Spek anchor, except that it was a shorter fluke that ensures proper fitting inside the boat's hull.
The popularity of this anchor has increased over the time due to the design improvements on hulls and the placement of anchor pockets.

MATERIAL QUALITY CONTROL
Similarly to the Spek Anchor, the Spek M is manufactured with GS200 cast steel in order to enhance the production process, making it more efficient due to the high ductility of the metal, and produce a high quality result. These are the anchor's mechanical properties:
PROPERTY | VALUE |
TENSILE STRENGTH (Rm, MPa) | 380 - 530 |
PROOF STRENGTH (Rp0.2, MPa) | 200 |
IMPACT ENERGY (KV, J) | 35 |
ELONGATION AT FRACTURE (%) | 25 |
The Spek M anchor comes in similar sizes as the regular Spek, but with the main difference of being produced up to 20000 kgs rather than 29000.
