Drop-In Anchor with Lip, Zinc Yellow Passivate: Performance Data
Hobson's two-page performance data for the zinc yellow passivate drop-in anchor with lip, part MDLMSYCM: a medium duty anchor for concrete that works at shallow embedment. An expansion wedge inside is driven down with a setting tool so the anchor grips the hole, and it can be loaded straight away once correctly installed.

Key things to remember
The essentials from this document in plain words. Check the full document before you rely on a figure.
- Sizes M6 x 25, M8 x 30, M10 x 30, M10 x 40 and M12 x 50. Carbon steel, zinc yellow passivate.
- Hole diameter and tightening torque: M6 8mm, 4Nm; M8 10mm, 8Nm; M10 12mm, 15Nm; M12 15mm, 35Nm. Hole depth equals the anchor length.
- Working load in tension in 32MPa non-cracked concrete (safety factors 2.5 steel and 3.0 concrete included): M6 x 25 2.3kN, M8 x 30 3.0kN, M10 x 30 3.0kN, M10 x 40 4.6kN, M12 x 50 6.5kN.
- Working load in shear in the same concrete depends on edge distance, for example M10 x 30: 6.2kN at 100mm, 8.2kN at 120mm, 10.3kN at 140mm. Design resistances in the same table already include strength reduction factors (0.60 concrete, 0.80 steel) and are for engineers.
- The red grip setting tool MATR10 is made for the M10 x 30 lipped anchor; MATMSZM setting tools are listed for the other sizes.
Who it helps: Plumbers, electricians, HVAC and ceiling installers hanging services from concrete.
