Metallics TP416SRC – Frequently Asked Questions
1) What thread size and length is the Metallics TP416SRC screw?
The TP416SRC is a 10-24 x 1-1/2 inch machine screw. The 10-24 designation means a #10 diameter with 24 threads per inch (a UNC machine screw thread), so it mates with a 10-24 tapped hole or a 10-24 nut, not a wood or sheet metal substrate.
2) Can the TP416SRC one-way screw be removed after it is installed?
Not with a normal screwdriver, and that is the point. The TP416SRC is a one-way tamper-resistant machine screw: the round head drives in clockwise and the slot geometry cams out if you try to back it off. Removal normally means a one-way screw extractor or drilling the head. If you need a fastener you will be servicing again, pick a conventional slotted or Phillips machine screw in the same 10-24 x 1-1/2 size instead.
3) Is the TP416SRC a self-tapping screw or does it need a tapped hole?
It is a machine screw, so it needs a mating 10-24 thread already there, either a tapped hole or a nut on the back side. It will not cut its own thread in sheet metal or wood. For an untapped cover, use a self-tapping or sheet metal tamper screw instead.
4) How many screws come in a pack of Metallics TP416SRC?
Each pack of TP416SRC is 100 pieces of the 10-24 x 1-1/2 one-way round head machine screw, so it is sold as a box quantity rather than individually.
5) What are one-way tamper-resistant machine screws like the TP416SRC used for in electrical work?
They are the fastener you use when you do not want the public opening what you just closed: exterior and public-area device covers, box covers, fixture canopies, signage and enclosures. The TP416SRC gives you that in a 10-24 thread at 1-1/2 inch length, which is enough reach to pass through a cover plus a spacer or gasket and still pick up a tapped hole behind it.
6) What head style is on the Metallics TP416SRC, and will it sit flush?
Round head, which seats on top of the surface rather than sinking into it. It will not sit flush and it does not want a countersunk hole. If you need a flush face, specify a flat head one-way screw in the same 10-24 x 1-1/2 size.
