Helix thickness. Note “K” is standard for MH220, MH313,
MH325, and MH352. See pg. 8
Magnum 2011 Product Catalog
Copyright 2011 – Magnum Piering, Inc.
Magnum engineers have performed calculations, finite element modeling, and accredited lab testing to develop helix thickness standards for punching shear and weld strength.
K = 3/8”For MH220, MH313, MH325, MH3521
M = 5/8” For MH425, MH431
O = 7/8” For MH530, MH536, MH625, and larger.

Size, style, and number of helical bearing plates needs to be determined based on traditional bearing capacity theory.
See pg. 8Magnum 2011 Product Catalog
Note:
S=Single Edge Helix (Standard)
D=Dual Edge Helix (DCE)
Copyright 2011 – Magnum Piering, Inc.
Magnum Piering, Inc. sizing charts are provided for cohesive soils, non-cohesive soils, and weak bedrock. Based on the SPT Blow Count and required ultimate capacity, they can be used to size helical bearing plates.
