Metallics TP418SRC – Frequently Asked Questions
1) Can the Metallics TP418SRC screw be removed after it is installed?
Not with a standard driver. The TP418SRC is a one-way tamper-resistant screw, meaning the head drives in clockwise but the slot geometry will not let a conventional screwdriver back it out. Use it where you want the fastening to stay put, such as public-area covers, enclosures, and signage. If you need to service the part later, pick a standard slotted or Phillips machine screw instead.
2) Is the TP418SRC a machine screw or a sheet metal screw?
It is a machine screw (MS), so it has a uniform 1/4-20 machine thread intended for a tapped hole or a nut, not a tapered self-threading point for sheet metal. If you are driving into unthreaded sheet, you need a tapping or sheet metal screw, not this one.
3) What driver do I need to install one-way tamper-resistant screws like the Metallics TP418SRC?
A standard flat-blade screwdriver drives it in. The one-way head has a slot with ramped sides, so the blade bites when turning clockwise and cams out when turned counterclockwise. No special bit is required for installation, which is part of why these get specified for tamper resistance in the field.
4) How many Metallics TP418SRC screws come in a box?
They are packed 100 pieces per box, all 1/4-20 x 1/2 inch one-way round head machine screws. That quantity suits a facility standardizing on one tamper-resistant fastener across multiple covers or panels rather than a single repair.
5) Where is the Metallics TP418SRC screw made?
The TP418SRC one-way machine screw is made in the USA, which matters on public and institutional jobs carrying domestic sourcing requirements.
