Elevator bucket bolts have a flat countersunk head that sits flush inside the bucket, preventing the bolt head from catching or abrading material as it flows through a bucket elevator. Supplied with nut and washer as a matched assembly.
Supplied in bulk to distributors, importers and hardware brands worldwide, including private-label packaging in the customer's own branding. Non-standard sizes and made-to-drawing variants are produced to order, with a material test certificate on every consignment.
