Metallics JFMB30 – Frequently Asked Questions
1) Are these brass screws or plated steel?
Brass. The BR in the Metallics JFMB30 description is brass, which is why electricians reach for it on grounding and bonding connections and in boxes where a non-magnetic, corrosion-resistant fastener is wanted. If you need the tensile strength of steel, a brass screw is not a substitute.
2) Will a 1/4-20 flat head screw sit flush in my cover plate or box?
A flat head screw is designed to seat flush, but only in a hole that has been countersunk for it. The JFMB30 has a flat head with a slotted drive; in a plain drilled hole without a countersink the head will stand proud. If the plate or enclosure is not countersunk, use a round or pan head 1/4-20 instead.
3) Is a machine screw the same as a sheet metal or self-tapping screw?
No. The JFMB30 is a machine screw, so it has a uniform straight thread with a blunt end and needs an existing tapped hole or a nut. It will not cut its own thread into sheet metal or form a thread in an untapped hole. For that you want a self-tapping or sheet metal screw, not this one.
4) What is the Metallics part number I should order for the 1/4-20 x 1 inch brass flat head screw?
Order Metallics JFMB30. That single part number covers the 1/4-20 x 1 inch brass flat head slotted machine screw in the 100 piece jar; there is no separate finish or length option to specify.
