Suppose you have previously ordered the correct screws for the job. In that case, you can ensure you get the right ones by using the manufacturer code to identify the correct item from our inventory. The manufacturer code is printed on the screw’s packaging. It is consistent across brands, so the characteristics of your screw will be the same, regardless of the manufacturer. For new projects that require fresh supplies, the choice of the screw will depend on its function, the size of the load it needs to bear, whether it will be inserted by hand or using a power tool and the materials it will be holding together. If you can’t work out which screw is going to work best, based on these variables, our expert customer care team is happy to offer appropriate product recommendations.
