Metallics JTEKDF1 – Frequently Asked Questions
1) What size and head type is the Metallics JTEKDF1 screw?
It's a #8 x 1/2 inch screw with a Phillips flat head driven by a #2 Phillips bit. The flat head sits flush when driven into a countersunk or self-formed seat, so it won't stand proud under a plate, bracket, or box ear.
2) Does the JTEKDF1 need a pilot hole in sheet metal?
No. The JTEKDF1 is a self-drilling screw, so the point cuts its own hole in sheet metal and taps the thread in one pass. That's what makes it quick for mounting to steel studs, strut, enclosures, and metal boxes without pre-drilling.
3) Are these Metallics self-drilling screws zinc plated for indoor electrical work?
They're steel with a zinc plating, which is the standard finish for interior electrical and MRO fastening. Zinc plating is a mild corrosion barrier for dry indoor conditions, not a marine or exterior-exposure coating, so for outdoor or damp locations choose a stainless or hot-dip fastener instead.
4) Is 1/2 inch long enough for the material I'm fastening into?
At 1/2 inch overall, a self-drilling #8 gives you only a short grip length once the point and the material thickness are accounted for. It suits thin-gauge sheet steel and light attachments where the fastener bites one layer, for example a strap, clip, or cover onto a steel stud or enclosure wall. If you're stacking two thicker layers or need thread engagement through a spacer, step up to a longer screw.
5) How many screws come in a jar of Metallics JTEKDF1?
Each jar holds 100 screws. The jar pack is the shop or van-stock format, so one unit covers a typical day of device and bracket mounting rather than a single job fix.
6) What is the exact part number to order these Metallics flat head self-drilling screws?
Order under Metallics part number JTEKDF1. That number covers the #8 x 1/2 inch Phillips flat head self-drilling screw, zinc plated steel, in the 100 count jar.
