Aluminium blind rivets with large flange heads, sized 4.8x21mm, engineered for heavy-duty fastening applications. These rivets feature a robust design that distributes load across a wider surface area, making them ideal for securing materials where standard rivets may prove insufficient. The large flange configuration provides enhanced grip and reduced risk of pull-through on softer substrates. Supplied in bulk quantities of 150 units, these fasteners deliver reliable, permanent joints in construction, automotive, and industrial assembly work. Corrosion-resistant aluminium construction ensures longevity in demanding environments.
