special fastener supplier & distributor orange county los angeles san diego inland empire southern california

Engineered Source Inc (DUNS# 626932016 & CAGE CODE 7LH48) was founded in 1990 by Greg Gosper, Bill Rupert, and Rod Lynch on the premise that quality, service, and on-time deliveries were crucial to developing lasting customer relationships. We know how important it is for manufacturers to produce their products consistently without delays or quality issues. Parts that cost pennies should never cause problems that cost dollars. Over the years, we have found success by maintaining that simple principle.


We are driven by one all-encompassing mission: to build and strengthen relationships with our customers by consistently striving to add value and be the absolute best.

At Engineered Source we strive to provide the best service to our customer base. To do this, we have established a culture that is committed to creating value, growing our business with integrity, and solving problems. We work relentlessly to provide our customers the most compelling experience and best possible service and selection. Our customers recognize and understand that we are doing everything in our power to help them succeed and maintain profitability.  


While fasteners are the foundation of our business, we have grown to include much, much more. As you browse our site you’ll find everything you need, from brass fittings, power cords, hose clamps, retaining rings, Bondhus tools, to everything in between. Our focus is on keeping OEMs working efficiently, regardless of what product category their needs fall under. From plastic to steel; whether the parts you need are threaded, stamped, formed, machined, or molded; whether they’re custom or common, Engineered Source can help you devise an efficient, effective inventory control strategy.
