Performance & Mechanical Specs of Lag Screws

Description A full-bodied bolt with spaced threads, hex head and a gimlet point.
Applications Electro-plated Zinc, Steel: For aqpplication in wood in non-corrosive environments

Hot-dip Galvanized, Steel : For application in corrosive environments

Stainless Steel: It has better corrosion resistance to galvanized steel bolts.
Material Steel: AISI 1006-1022 or equivalent steel

Stainless Steel: 18-8 stainless
Heat Treatment Stainless: The austenitic alloys gain their strength through hardening during the manufacturing process, as shown in the below hardness properties. Annealing is the only heat treatment available normally on austentic stainless alloys. It is done at approximately 1900 Degrees (F) to a dead soft condition. It is not normally thermally reversible.
Hardness Steel: Rockwell B70-B100

Stainless Steel: 100,000 – 125,000 psi
Minimum Length of Thread Minimum length of thread should be equal to 1/2 of the nominal screw length + 0.50 inches, or 5.00 inches, whichever is shorter. Screws which are too short for the formula ssould be threaded as close to the head as practicable.
