The engineering support you’ve been looking for

Even though timely customer service and expert product support should be essential for doing business, these days it seems to be the exception and not the rule. Getting the ongoing support you need is especially critical when you have a tricky engineering challenge to work through. At that point, you don’t just need a part – you need a partner.

At Fredericks, our heritage of support goes back more than 80 years, working side-by-side with OEM customers across the world in a wide range of markets and literally hundreds of applications. In that time, you could say we’ve learned a thing or two about angle measurement, vacuum measurement and advanced manufacturing techniques. Our team of designers and engineers can bring that experience to bear for you. We’ll develop high quality, cost-effective products and components that are critical to solving your most challenging OEM design problems. Yeah, we know…talk is cheap. So we invite you to check us out. Kick the tires. We believe you’ll find the engineering partner you need at Fredericks.
