December, 2010 Altenloh, Brinck & Co. U.S. Inc. received evaluation report ESR-1782 for SPAX® PowerLags® structural fasteners. The report covers the largest range of structural lag fasteners in the industry including 4 diameters (1/4", 5/16", 3/8" and 1/2") and lengths ranging from 2" to 24". Building contractors will be able to utilize test data values for SPAX® products evaluated in 7 species of hard and soft wood products found across the country. In addition, SPAX® specialized exterior coatings HCR® and HCR-X™ were evaluated and approved for use in treated lumber. What this means for contractors is SPAX® PowerLags® can be used to replace the conventional lag and it is not necessary to pre-drill (1/4" and 5/16") during installation.
