Flat nut fasteners are one-piece, self-locking, spring-steel fasteners that replace threaded nuts, lockwashers and spanner washers. On many applications they eliminate time consuming assembly operations. They are fast and easy to apply while providing maximum holding power at minimum cost per fastener. They can never shake loose from vibration, yet can be easily loosened when desired.

In addition to our standard products listed here, we specialize in manufacturing custom designs for unique applications. Our products are horizontally stamped in fourslide machines. Our staff will help you with your design, provide you with pricing and produce a final part print for your approval. Please contact us for production run minimums (sales@e-qual-fast.com).
