High Performance Thread Rolling Screw
Benefits
Creates high quality mating threads
Eliminates tapping costs
Eliminates chips and burrs
Resists vibrational loosening
Features
Patented 360° asymmetrical thread-forming lobes
Spiral thread form for ease of assembly
Patented "Vibrational Resistant" thread forming screw
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 rolls 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.
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, the improved bearing surface at the shoulder/thread transition radius has proven beneficial when used as a compression-limiting shoulder bolt.
Heat Treatment
- Case hardening is considered the standard heat treatment for ROLOK® fasteners in general steel applications. (Core RC 28-38, Surface RC 45 Minimum)
- 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
Various coating and plating options can be applied to ROLOK® fasteners to meet specific customer requirements for corrosion resistance and joint performance.
