Metallics TP821SOC – Frequently Asked Questions
1) What driver do I need for the Metallics TP821SOC spanner head screws?
These take a spanner bit, also called a snake eye: two round holes in the face of the head instead of a slot or cross recess. A flat blade or Phillips will not drive them. That is the point of the drive, it is a tamper-resistant screw meant to keep covers and plates from being removed with common tools, so order the matching spanner bit or driver separately if your crew does not already carry one.
2) Are these Metallics screws stainless steel, and can they be used outdoors?
They are 18-8 stainless, the common austenitic grade used for general corrosion resistance, so they hold up in damp and outdoor-exposed locations far better than plated carbon steel. For heavy chloride exposure (coastal or pool chemical rooms) a 316 stainless fastener is the better choice.
3) Is the TP821SOC head flat or raised, and will it sit flush?
It is an oval head. An oval head seats in an 82 degree countersunk hole like a flat head but leaves a low domed crown above the surface, so it does not finish dead flush. If you need the fastener fully flush with a plate or panel face, specify a flat head instead.
4) How many screws come in a box of Metallics TP821SOC?
100 pieces per box. For an electrician standardizing tamper-resistant cover plates or device plates across a building, that covers roughly 50 two-screw plates, so order by plate count rather than by box.
5) What is the Metallics part number for the 10-24 x 3/4 oval spanner tamper-resistant screw?
Metallics catalogs it as TP821SOC. That is the number to quote for the 18-8 stainless, 10-24 by 3/4 inch oval head spanner drive machine screw in the 100 piece box.
