Metallics TP413SRC – Frequently Asked Questions
1) Can a one-way tamper resistant screw like the TP413SRC be removed after it's installed?
No, and that is the point of it. One-way (TR) screws drive in with an ordinary flat blade screwdriver, but the head is ramped so the blade slips out of the slot when you try to back it out. Plan on it being permanent. If you need a fastener you can service later, specify a standard slotted or combination head machine screw in 10-24 x 3/4 instead.
2) What are one-way tamper resistant screws used for in electrical work?
They're used where a cover, plate, or enclosure needs to stay shut in a public or unsupervised space: pull box and junction box covers, panel trim, device plates, and fixture covers in corridors, stairwells, schools, transit areas, and multi-family common areas. The TP413SRC is a 10-24 x 3/4 round head version for those jobs, carried as an electrical fastener.
3) Will a 10-24 x 3/4 machine screw thread into a standard electrical box cover?
Yes, provided the box or cover ear is tapped 10-24, which is the common machine screw thread on steel outlet, device, and pull box covers. The 3/4 inch length gives enough reach for a cover plus a gasket or a raised plaster ring; on a thin single cover it will protrude through the tapped ear, which is usually fine but worth checking if there is wire behind it.
4) What driver do I need for the Metallics TP413SRC one-way screw?
A standard flat blade screwdriver sized to the slot drives it in. No special bit is needed for installation, which is why one-way screws get specified for crews: nothing extra to carry. There is no driver that backs them out, so removal means drilling or gripping the head.
5) Is the Metallics TP413SRC screw made in the USA and how many come in a box?
Yes, the TP413SRC is USA made and packed 100 screws per box. That matters on public and institutional work where domestic sourcing is a condition of the contract.
