Landscaping Screws Size Chart
Landscaping screws are becoming more and more popular over the years and we now stock a full range of both 16 gauge and 18 gauge screws.
These are to be used when you've got thick, solid timbers that need pulling together such as retaining walls etc.
Our 16 gauge landscaping screws have 6.8mm thick shanks
18 gauge have 7.5mm thick shanks. 18 gauge is by far the most popular as generally when needing a landscaping screw you'll often be using them in replacement for bolts so thicker is generally better. You'll get increased torsion and load ratings from an 18 gauge over a 16 gauge just due to the fact that the shank is almost 20% thicker.
