Metallics JRM44SLT – Frequently Asked Questions

1) Will a 1/4-20 machine screw thread into a standard 1/4-20 tapped box or strap?
Yes. The Metallics JRM44SLT is a 1/4-20 machine screw, 20 threads per inch, so it mates with any 1/4-20 tapped hole or nut. Machine threads like this are meant for pre-tapped metal and nuts, not for driving into wood or drywall.
2) Does a round head screw sit flush, or will the head stand proud of the surface?
It stands proud. Round head screws have a domed head that bears on top of the material, with a head width of 0.443 to 0.472 in. and head height of 0.16 to 0.175 in. on the JRM44SLT. If you need the head buried in a countersunk hole, use a flat head screw instead.
3) Do these Metallics screws qualify for Buy American or ARRA funded projects?
No. The JRM44SLT is not Buy American compliant and not ARRA compliant, with multiple countries of origin. On a federally funded job with domestic sourcing requirements you will need a domestically produced fastener.
4) How much grip length do I get from a 5/8 inch machine screw?
The JRM44SLT is 5/8 inch long measured under the round head, since round head screws are measured from the bearing surface down. Deduct the thickness of whatever you are fastening through to see how much thread is left to engage the tapped hole or nut.
5) What screwdriver bit do I need for these Metallics JRM screws?
A flat blade. The drive is slotted, with a slot width of 0.064 to 0.075 in. and slot depth of 0.082 to 0.109 in., so a keystone or cabinet tip in that thickness range seats properly. An oversized blade will ride out and chew the slot.
6) How strong is this 1/4-20 steel machine screw?
Minimum tensile strength is 60,000 psi, with hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is general purpose fastener strength, fine for mounting boxes, straps, covers and fixtures, but not a substitute for a graded structural bolt in a load bearing connection.
7) Is a zinc plated steel machine screw okay outdoors or in a damp location?
The JRM44SLT is steel with a zinc finish, which gives moderate corrosion resistance for dry interior and protected work. For wet, washdown, coastal or chemical exposure, specify a stainless machine screw in the same 1/4-20 x 5/8 size instead.
8) How are these screws packaged and what is the smallest quantity I can buy?
They ship in a jar, with a minimum order of 100 count. So you are buying a 100 piece jar rather than loose singles, which suits a van stock or shop bin item.
9) Can I get this JRM screw in other lengths or larger quantities?
Yes, Metallics offers other sizes and quantities in the JRM machine screw series by request. The JRM44SLT itself is the 1/4-20 x 5/8 in. round head slotted version in steel zinc.
