Description
The SpecialInsert F1 Series are female adhesive-bonded fasteners featuring internal threads for bolted connections where access from one side is limited. Designed for adhesive bonding instead of drilling or welding, these zinc-plated and stainless-steel fasteners create reliable threaded anchor points on metal, composite, and plastic substrates.
The F1 family includes round, rectangular, and square base options — allowing flexible installation across signage, marine, aerospace, and OEM applications. As part of our Core Range, these models are stocked for fast delivery and consistent performance in structural bonding applications.
