Frequently Asked Questions
Can I use these screws with impact drivers?
Can I use these screws with impact drivers?
Yes, most Simpson construction screws are designed for use with impact drivers. However, always start at lower torque settings and adjust as needed to prevent over-driving or stripping. Self-drilling and structural screws particularly benefit from the consistent torque delivery of quality impact drivers.
How do I know which screw length to use?
How do I know which screw length to use?
The general rule is that the screw should penetrate at least 1.5 times the thickness of the material being attached. For structural applications, follow local building codes and Simpson's published specifications.
What's the difference between self-drilling and self-tapping screws?
What's the difference between self-drilling and self-tapping screws?
Self-drilling screws have a drill point that cuts through metal without pre-drilling. Self-tapping screws require a pre-drilled hole but cut their own threads. Simpson's self-drilling screws eliminate the pre-drilling step in most steel applications up to specified thicknesses.
Can I use wood screws in engineered lumber like LVL or LSL?
Can I use wood screws in engineered lumber like LVL or LSL?
Yes, but engineered lumber is typically denser than solid wood. You may need slightly more driving torque, and pilot holes might be beneficial near edges. Simpson structural wood screws are specifically tested with engineered lumber products.
