Growth of a Distributor

BelMetric.com’s American dream took off in Massachusetts in 1976. After gaining valuable experience at legacy distributor Zelenda Metric, founder Ralph Lomando hit the road in a repurposed mail truck—delivering high-demand metric fasteners to performance shops and dealerships. As word spread and demand surged, Ralph established global supplier partnerships to grow the catalog and fill critical gaps in the U.S. market. Today, BelMetric.com remains an independent, owner-operated business—known for its deep inventory, worldwide sourcing, and responsive service. Once the best-kept secret in metric fasteners... now, the secret’s out.

Elevating the B2B Experience

BelMetric.com offers one of the most comprehensive selections of metric hardware in the U.S. The catalog features rare DIN and ISO parts, a wide range of JIS fasteners, and less common metric items including OEM clamps, hose, electrical connectors and fittings. Distributors can access CAD files, technical drawings, and detailed spec sheets for nearly every SKU. High-resolution product photos from BelMetric’s in-house studio support confident, accurate buying. Company accounts streamline B2B purchasing with multi-user access, centralized shopping lists, and quote history tracking. BelMetric.com gives distributors the tools they need to support their customers and close the sale.
