Minerallac 62911SSJ – Frequently Asked Questions

1) What lengths does the Minerallac 1/4-20 stainless machine screw come in?
Three lengths: 3/4 inch (MPN 62911SSJ), 1 inch (62915SSJ), and 1-1/4 inch (62919SSJ). All three are 1/4-20 coarse thread, round head, Phillips drive, in Type 18-8 stainless steel. Pick the length by how thick your material stack is plus enough thread left to fully engage the nut or tapped hole.
2) Do these screws come with nuts, or do I need a tapped hole?
The screws are sold on their own, no nuts included. They are machine screws, so they go into a pre-tapped 1/4-20 hole or take a separate 1/4-20 nut behind the panel. Order nuts and any washers you need as separate line items.
3) What size driver do I need for these 1/4-20 round head Phillips screws?
A #3 Phillips bit. A #2, which is what most cordless kits come loaded with, will sit loose in the recess and cam out, and stainless recesses tear up quickly once the bit slips. Keep a #3 in the pouch if you are running these on a panel or enclosure job.
4) Is 18-8 stainless OK for outdoor or damp electrical work?
Type 18-8 stainless is the standard corrosion-resistant choice for indoor and outdoor service, and these are called out for marine and outdoor equipment as well as electrical enclosures and panels. For salt-spray immersion duty a 316 alloy is the step up, but for exterior enclosures, rooftop HVAC, and damp mechanical rooms 18-8 is the usual spec.
5) Will a 1/4-20 machine screw thread into a self-tapping sheet metal hole?
No. A machine screw needs a matching 1/4-20 female thread, either cut into the part or supplied by a nut. If your hole is just a drilled or punched opening in sheet metal with no thread, you need a self-drilling or sheet metal screw instead, or you need to tap the hole to 1/4-20 first.
6) Why choose a round head instead of a flat head screw for enclosure mounting?
Round head sits proud on the surface and spreads load across a bearing face, so it works on plain drilled holes with no countersink prep. A flat head needs a countersunk or chamfered hole to seat flush. If your panel or bracket is not countersunk, round head is the one that will seat correctly.
7) Can I run these stainless screws in with an impact driver?
Go easy. Stainless threads gall if you drive them hot and fast, and over-torquing can strip the tapped hole or twist the screw. Use a clutch setting or finish by hand, and confirm the head is seated without flexing the panel. A #3 Phillips bit is required to keep the recess intact.
