Metallics TP422SRC – Frequently Asked Questions
1) What is a one-way screw and when should I use one instead of a standard machine screw?
A one-way screw like the Metallics TP422SRC has a tamper resistant head that drives in with an ordinary flat blade but cams out when you try to back it off, so it cannot be removed with common tools. Use it where you want a fastener to stay put in a public or unsupervised location, such as covers, plates, signage, and enclosure lids. If you need to service the assembly routinely, pick a conventional slotted or Phillips 1/4-20 machine screw instead, because taking a one-way screw out usually means drilling it or gripping the head with an extraction tool.
2) Are these screws sold individually or by the box?
The Metallics TP422SRC one-way screws come packaged 100 pieces per box. For a property manager or MRO stockroom standardizing tamper resistant covers across a building, one box covers a lot of plates, and keeping a single 1/4-20 x 1-1/2 size on the shelf keeps the install consistent.
3) What is the right way to remove a one-way tamper screw that is already installed?
A one-way head will not back out with a screwdriver by design. In the field, electricians either grip the round head with locking pliers or a screw extractor socket and turn it out, or drill the head off and punch the remainder through. Plan for that before specifying the TP422SRC on anything you expect to open regularly; for serviceable covers, a standard 1/4-20 x 1-1/2 machine screw is the better call.
