How much allowable load will the lag support if embedded 3" into Douglas Fir-Larch # 2 lumber or Hem Fir # 2 lumber and supporting 1/4" steel plate
Asked by: Greg
Hello, We do not do testing through a pre-drilled hole. I.E. the fabricated bracket. The following are results with a 4 to 1 safety factor applied. Pull out value in Douglas Fir is 259 / in of penetration which gives around 750 lbs per fastener. Hem Fir is 210 / in of penetration which gives around 600 lbs per fastener. More comprehensive details are available in our ICC report 1782. Thanks for being a SPAX customer
