2 Features / Benefits ROLOK thread rolling fasteners for metals offer a unique spiral thread form to achieve excellent drive-to-strip performance in many challenging applications resulting in lower in-place fastening costs. ROLOK Benefits Include: 360 degree asymmetrical spiral profile that roll forms high quality mating threads Eliminates costs associated with tapping holes Excellent drive-to-strip ratio High resistance to vibration loosening (meets or exceeds IFI 124/524) Virtually eliminates chips and debris Increases assembly line productivity Use with a variety of nut materials ROLOK fasteners offer improved drive-to-strip ratios compared with other common thread rolling designs. Drive Torque Strip Torque ROLOK Drive Torque Strip Torque Other Fasteners Performance in Unique Applications ROLOK fasteners have been proven to be especially useful in aluminum C-channels and other similar designs due to their spiral profile body which gives improved engagement and more repeatable performance. Additionally, improved bearing surface at shoulder/thread transition radius has proven beneficial when used as a compression limiting shoulder bolt. 2

(Core RC 28-38, Surface RC 45 ) Through hardening may be used for applications in soft white metals such as aluminum or zinc alloys. Induction hardening should be used to address high strength or structural safety steel applications. Coatings and Platings A wide variety of coating and plating options can be applied to ROLOK fasteners to meet specific customer requirements for corrosion resistance and joint performance. 3
