Metallics TP229SFC – Frequently Asked Questions
1) What driver do I need for the Metallics TP229SFC tamper-resistant screw?
The TP229SFC takes a pin-in-star (pin-in-Torx) tamper-resistant bit. A standard Torx bit will not seat because the recess has a center pin, so you need the matching pin-in-star driver on hand before you start the install. That center pin is the whole point of the screw: it keeps the public from backing fasteners out of cover plates, enclosures and fixture trims with a common bit.
2) Is the 10-32 x 3/8 star pin screw a machine screw or a sheet metal screw?
It is a machine screw. The 10-32 designation is a uniform machine screw thread, so it threads into an existing tapped hole, a tapped boss, or a nut, not into raw sheet metal. If your hole is not already tapped 10-32, you will need to tap it or use a sheet metal or self-drilling screw instead.
3) Will a 10-32 x 3/8 flat head screw sit flush, or does it stick above the surface?
Flat head means a countersunk head, so it finishes flush when the hole is countersunk to match an 82 degree flat head. On a plate or trim with a flat, un-countersunk hole the head will stand proud. The 3/8 inch length is measured from the surface down on a flat head, so you get 3/8 inch of total engagement depth, which suits thin plates and cover applications rather than thick stacked material.
4) Are these 18-8 stainless screws OK for outdoor or damp electrical enclosures?
18-8 stainless (the 300 series austenitic grade used for 304-type fasteners) holds up well to weather and washdown, which is why it is specified for exterior cover plates, outdoor enclosures and damp locations where a plated steel screw would rust and seize. It is not the right choice for heavy chloride exposure such as coastal or pool chemical environments, where a 316 fastener is the better call.
5) What is the exact part number to order for a 10-32 x 3/8 pin-in-star tamper screw in stainless?
Order Metallics TP229SFC. The number covers the 10-32 x 3/8 inch flat head pin-in-star tamper-resistant machine screw in 18-8 stainless, 100 per box. It is a single-configuration item, so there is no finish or length option to specify on the order.
6) How many Metallics TP229SFC screws come in a box?
TP229SFC ships 100 pieces to the box. That quantity is aimed at MRO and facility crews standardizing tamper-resistant hardware across many devices at once rather than at a single-device repair, and it keeps one pin-in-star bit size covering the whole run.
