Technical Specifications
Leadwood screw anchors are available in three lengths- 3/4", 1", and 1 1/2". A longer leadwood screw anchor should be used when installing into softer base materials. These concrete fasteners are best used in light duty fastening applications with dead loads only. Anchors are made of zinc alloy, die cast material. All leadwood screws from Concrete Fasteners.com are also rust resistant and can withhold 3000 PSI concrete tensions of up to 415.

*Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally
accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio. *Tested by ATEC in accordance
with ASTM E488-90 and ICBO Minimum embedment for satisfactory anchor performance is 4-1/2 bolt diameters. Deeper embedment will
yield higher tension and shear capacity.
