💡 How do coarse pitch external wood screws handle structural shear loads better than smooth pin fasteners?
- Coarse lead angle threads engage outer bark rings creating maximum bearing surface area for lateral force distribution during high wind events
- Pre hardened steel alloys resist tensile failure while the truss head design distributes shear stress across a wider flange contact patch
- A handy trait of self tapping pilot geometry is displacing cellulose fibers cleanly instead of prying them outward like blunt pins
- Weather sealed zinc alloy coatings stop galvanic corrosion pathways from forming between dissimilar metals when mounting aluminum rails to timber posts
