FREQUENTLY ASKED QUESTIONS Q: What type of glue do I need to fasten the knob to the screw? A: No glue is required with the Shear-Loc process.
You simply press the knob completely over the screw, this creates a "
cold formed" junction between the knob and the screw. Q: Just how strong is the connection between the knob and the screw. A: If assembled properly the thumb screw will have
more than adequate strength for most common hand manipulated applications.(
Call 800-638-1830 for samples to test.) Q: What is the stable temperature range for Shear-Loc knobs and what material are they made of. A: Shear-Loc knobs are stable in temperatures ranging
from freezing to 83°C/180°F, (caution: not autoclaveable) and are
molded of acetal resin. Q: Are Shear-Loc knobs made from a UV light stable material? A: No. Shear-Loc knobs will fade when subjected to direct sun light,they may even take on a chalky appearance. For the most part this is a cosmetic problem and the thumbscrew should continue to function properly.( See what's new/etc page.) Q: How are Shear-Loc knobs sold? A:Shear-Loc knobs and thumbscrews are sold in package quantities, and assortment kits are sold individually. Q: I have been told that some of the Shear-Loc line is offered in a natural color. What does that mean? A: We stock most size knobs in natural material which
has a milky white appearance and contains no color pigment. Call
800-638-1830 and ask for natural samples. Q: In your catalog you mentioned that the thread class is 3A, can I get them with a 2A thread? A: The Shear-Loc process utilizes a standard socket
head cap screw that has a class 3A thread. They are not available off
the shelf with a 2A thread. This doesn't really pose much of a problem as
long as the design engineer is aware of it. Class 3A taps are
extremely common and readily available. NOTE extra caution should be taken
when the screw is to be plated as it could easily push the 3A thread out of
tolerance. Q: In what country of origin are the knobs and screw manufactured? A: The knobs are made in the U.S.A. and in most
cases the screws are imported. If you also want the screws made in the
U.S.A. we will be glad to source them for you. Call 800-638-1830
with your requirement. Q: How can we be sure the standard line of Shear-Loc thumbscrews will function and endure on our current and planned products. A: Ask for FREE* test samples, Please don't assume any component will satisfy your customers expectation without testing. Call 800-638-1830 and we'll send samples for testing. (*for qualified customers) Q: On socket head cap screws that are not fully threaded what is the minimum thread that the screw will have ?
