1-1/2" Square Lock Washers

Square Self Locking Washers are used to secure insulation onto self-stick or perforated base pins.  The insulation washers are 1-1/2" x 1-1/2" squares of galvanized steel. Each of these square lock washers fits 12 gauge pins (all insulation pins and clips sold on our site).

When installing on softer batt insulation make sure not to compress the insulation (causes loss of R-Value). Check out these bulk washers for sale today!
