Set includes ¾" self-drilling #8 screws and 1.5" metal self-locking insulation washers. The locking washers are specially designed to secure insulation material in place and create a tight seal. This combination of screws & washers is used for installing BlueTex™ directly on both metal and wood frames.

On average an install will typically require 14 - 20 screws per 100 sq ft of insulation. The 100-pack has 100 of EACH of the screws and washers (200 pieces total). The 500-pack has 500 of EACH of the screws and washers (1,000 pieces total). See the chart for recommended quantities.

The standard color for these is a shiny silver that blends in directly with the aluminum side of the BlueTex™. If you're using the white side of the BlueTex™ for your interior layer, you can pre-paint these with some white spray paint so they blend in (see photo).
