When Secondary is Primary

In addition to being self-sealing, through its unique groove and o-ring technology, CSFI Manufacturing Company provides its customers with numerous secondary processing options from heat-treating, plating and coating, to testing, inspection and packaging. Over its twenty-five years in business CSFI has cultivated relationships with the best providers of secondary processing in the fastening industry. CSFI emphasizes "shopping local" in its sourcing to shorten the supply chain as much as possible so that it can pass its savings in time and money on to its customers. CSFI's local heat treating partner is NADCAP approved and AQS Certified. Its coating and plating providers are both ISO and AS 9100 Certified. CSFI also provides full quality inspection, pressure and torque testing and packaging per customer specifications.

CSFI fasteners can be heat treated for hardness and high temperature resilience, the survive the most challenging conditions. Fasteners can also be provided self-locking and anti-vibration features such as patch, pellet, strip and epoxy. Additionally CSFI parts can be plated for abrasion, heat and erosion resistance.
