SinuLOC™

SinuLOC™

Eliminate Patches and Adhesives

SinuLOC™ curved thread fastener is the integration of a sine wave at a specified location on an externally threaded fastener which is a result of increasing the fastener’s pitch diameter. The addition of the sine wave creates a mechanical interference between the internal and external threads to simply stay tight.

 

SinuLOC™ Benefits

COST SAVINGS – SinuLOC™ – curved thread fastener is applied during the thread rolling process before heat treating and plating. This eliminates costs incurred by secondary manufacturing processes, the need to ship unfinished goods and downstream quality control.

MECHANICAL INTERFERENCE FIT – SinuLOC™ curved thread fastener creates a mechanical interference on the thread flanks by increasing the pitch diameter which fills the thread clearance.

UNIVERSAL PERFORMANCE – SinuLOC™ curved thread fastener can be used on any standard pitch diameter threaded fastener to prevent joint loosening.

TORQUE TENSION – SinuLOC™ curved thread fastener maintains the torque tension relationship of standard machine thread.

SERVICEABILITY – SinuLOC™ curved thread fastener offers the ability to be installed and uninstalled multiple times.

ERGONOMICS – SinuLOC™ curved thread fastener allows for maximum free-spinning by positioning the interference fit where it is needed.

ENVIRONMENT – SinuLOC™ curved thread fastener is resistant to vibration, high heat (1200°F), and lubricants and does not create exposed abraded surfaces which cause corrosion.
