LMAZ Light Mudsill Anchor in ZMAX®

LMAZ

On This Page

The LMAZ is a mudsill anchor that provides an economical replacement for 1/2" sill plate anchor bolts. The unique design provides installation flexibility, eliminating problems associated with wall framing alignment interfering with foundation anchors. The LMAZ has a ZMAX coating, a thicker galvanized finish that helps extend the service life of the connector.

Key Features

  • Suitable for stem wall or slab foundations
  • One-piece design, so there are no nuts and washers to lose
  • Legs may be installed into mudsill or stud with no load reduction

Material

  • 18 gauge

Finish

  • ZMAX; see Corrosion Information

Installation

  • Use all specified fasteners; see General Notes.
  • Not for use where a horizontal cold joint exists between the slab and foundation wall or footing beneath, unless provisions are made to transfer the load.
  • Install while concrete is still wet. Do not attach mudsill until concrete cures.

Load Tables

    These products are available with additional corrosion protection.

LMAZ/MAB/MASB Mudsill Anchors Load Table
  1. Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
  2. For uplift loads, provide attachment from mudsill to building's structural components to prevent cross-grain bending.
  3. LMAZ installed attached to the stud has no load reduction for parallel and perpendicular loads and an uplift of 600 lb. for LMA4 and 835 lb. for LMA6.
  4. For concrete stem wall applications, allowable loads are based on a minimum concrete stem wall width of 6".
  5. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.

Prescriptive Anchor Spacing

    These products are available with additional corrosion protection.

Prescriptive Anchor Spacing
  1. "Prescriptive" denotes designs per the IRC or conventional provisions of the IBC for wind speeds 140 mph or less, or for Seismic Design Category D and less (SDC E and less in IBC).
  2. Spacing is based on parallel-to-plate load direction only.
  3. Place anchors not more than 12" from the end of sill and splices per code.
  4. Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
  5. Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
  6. Spacings apply to DF, SP, and HF sill plates.
