Fasten Without Marring Shaft Using Shaftloc®

Product Announcement from Stock Drive Products & Sterling Instrument - SDP/SI


Hicksville, NY  Shaftloc® Fastening Device is Simply Superior!

Shaftloc® is a patented rotating component fastening device, produced by SDP/SI (ISO 9001 + AS9100 Registered). A surprisingly simple design, it eliminates all the disadvantages of traditional methods for fastening components to shafts.

There are several different styles available for the Shaftloc® Fastener, but they all feature a simple two-piece construction with corresponding male and female threads. The sleeves slide over the shaft on either side of the component to be secured. The threads are assymetrical so that the two sleeves wedge together around the shaft, holding the part between them. Hex heads make it easy to tighten the Shaftloc® sufficiently, and to unscrew it to make adjustments as needed.

Because the design is so simple, it is very easy to install and low cost. Because there are no set screws, it can be reused and adjusted many times over without ever marring the shaft. The shallow angle of the thread produces large amplification of forces, resulting in substantial torque transmission capability between the component and the shaft.

SDP/SI offers a wide variety of inch and metric small mechanical components for the design engineer and OEM. Standard components can easily be located and purchased in one convenient place, shop online 24/7. The engineer not only meets all his component requirements, but saves valuable time by not having to search other sources.
