Metallics JFMB108 – Frequently Asked Questions
1) What do the abbreviations in the Metallics JFMB108 screw description mean?
JFMB108 is a 10-24 x 1/4 inch machine screw with a flat head and a slotted drive, in brass. FH is flat head (countersunk, sits flush in a chamfered hole), SL is the slotted driver recess, MS is machine screw, and BR is brass. It comes 100 to a jar.
2) Is the Metallics 10-24 x 1/4 screw long enough to replace a standard device or cover screw?
Only for shallow applications. The threaded length is 1/4 inch, which is shorter than the typical 1/2 inch device screw shipped with receptacles and switches. Use it where you only need a few threads of engagement, such as fastening a ring, clamp, or bonding lug to a tapped hole. For mounting a device through a plaster ring and into a box, you will want a longer 10-24 machine screw.
3) Why choose a brass machine screw instead of steel for electrical work?
Brass conducts, so it is the usual pick for grounding and bonding connections and for terminal or lug hardware where the fastener is part of the electrical path. It also resists corrosion better than plain steel in damp locations. The JFMB108 is a brass 10-24 x 1/4 screw, which is why it shows up in bonding and device-mounting kits rather than as a general structural fastener.
4) Does the flat head on the JFMB108 screw sit flush, and does the hole need to be countersunk?
A flat head machine screw is designed to seat flush, but only in a countersunk or chamfered hole. In a plain punched hole the head will stand proud. If you need a flush finish on a cover plate or ring that is not countersunk, pick a different head style; if the part is already chamfered, the 10-24 x 1/4 flat head slotted brass screw will sit level with the surface.
5) How many screws come in a jar of Metallics JFMB108, and is that a practical quantity for a service truck?
Each jar holds 100 of the 10-24 x 1/4 brass flat head screws. The jar pack is meant for truck stock and shop bins, where you pull a few screws at a time for device, lug, and bonding work rather than buying loose counts per job.
6) What part number should I order for the Metallics brass 10-24 flat head machine screw?
Order it as Metallics JFMB108. That is the manufacturer part number for the 10-24 x 1/4 inch slotted flat head brass machine screw supplied 100 per jar. There is a single configuration, so there is no finish, length, or drive option to specify.
