Metallics JRM136SLT – Frequently Asked Questions
1) Will the round head sit flush, or does it stand above the surface?
It stands above. A round head has a domed top and a flat bearing underside, so it seats on the surface rather than sinking in. Head height runs 0.107 to 0.12 in. and head diameter 0.287 to 0.309 in., so plan for about an eighth of an inch of standoff. If you need the head buried, use a flat head screw in a countersunk hole instead.
2) Are zinc plated steel machine screws OK outdoors or in damp locations?
Zinc plating on carbon steel is a mild corrosion coating meant for dry interior service. It will handle occasional humidity, but in wet locations, exterior boxes, coastal air, or anywhere washdown chemicals reach it, the plating gives up and the screw rusts. Specify stainless 8-32 machine screws for those openings.
3) Do these 8-32 screws need a nut, or do they thread into tapped holes?
Machine screws carry a straight, fully formed 32 threads per inch machine thread, so they go into a tapped hole or take a nut. They are not self tapping and will not hold in a drilled hole in sheet metal or in wood. For a nut, match it to 8-32.
4) Is the Metallics JRM136SLT Buy American and ARRA compliant for a government or institutional job?
The JRM136SLT is flagged compliant on both Buy American and ARRA. Country of origin is China, so if your spec enforces domestic melt and manufacture rather than the ARRA/Buy American compliance flag, verify against the project's exact clause before you submit it.
5) How many 8-32 x 5/8 round head machine screws come in a pack?
They ship 100 to a jar, which is the minimum order quantity. Handy for a service van or a shop drawer rather than a one-off repair.
6) How strong are these screws, and what steel are they made from?
Minimum tensile strength is 60,000 psi, with a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial machine screw strength, fine for device mounting, panel hardware, plates, and brackets. It is not a structural fastener, so do not substitute one into a load path that calls for a graded bolt.
7) How much does a jar of 100 of these 8-32 screws weigh?
About 0.45 lbs per jar, with the container measuring 3 in. by 3 in. by 2.15 in. Small enough to keep several lengths side by side in a van bin.
