Precision Screw Machining of Steel Bleeder Screws for an Automotive Application

At Madison Tool, we specialize in high quality screw machining. Our reputation brought this automotive industry customer to us with the bleeder screw project highlighted here. The customer’s previous supplier was not able to provide the precision, quality, and consistency that they required, so they looked to us for help. This project represents a long term commitment from the customer, and high volume manufacturing from us.

The customer had several objectives in regards to the production schedule; they needed to stock their new warehouse on the west coast within a short timeframe, and required weekly deliveries to maintain their production schedule. To meet these requirements we produce these bleeder screws at a rate of 100,000 per day.

Madison Tool is well positioned to meet various bleeder screw project requirements, supplying 89 different bleeder screws from inventory, in a range of screw sizes from 3/16” to 7/8”. We can provide various coatings and surface treatments, brass seat inserts, and bleeder screws with O-rings. Our bleeder screws are commonly used in many automotive applications including, ATVs, snow mobiles, military vehicles, forklifts, motorcycles, and even mining equipment. Our company will also ship worldwide. We currently ship bleeder screws to South America, India, Canada, and Spain.
