Metallics JTEKDF11 – Frequently Asked Questions
1) Are these Metallics screws okay for damp or outdoor electrical work?
The JTEKDF11 is steel with a zinc plating, which is a general-purpose indoor and dry-location coating. It resists incidental moisture and handling corrosion but is not a stainless or hot-dip galvanized fastener, so for wet, coastal, or sustained outdoor exposure you want a stainless self-drilling screw instead.
2) What driver do I need for the JTEKDF11 self-drilling screw?
A Phillips driver. The JTEKDF11 is a Phillips flat head screw, so it sinks flush into a countersunk hole or a prepped channel rather than sitting proud like a hex washer head. If you need a hex-drive screw for faster run-in with an impact driver, this is not that fastener.
3) Will a flat head self-drilling screw sit flush, or will it leave a bump under my panel?
Flat head means a countersunk profile, so the JTEKDF11 finishes flush with the surface when driven into a countersunk or soft-enough substrate. That matters where a cover plate, trim, or panel seats on top of the fastener. Where you want a bearing surface against sheet metal instead, a hex washer head or pan head screw is the better choice.
4) What is the exact part number to order the 1/4 x 1-1/2 Phillips flat head self-drilling screw from Metallics?
Order Metallics part number JTEKDF11. That covers the 1/4 inch by 1-1/2 inch Phillips flat head, #3 self-drill point, zinc-plated steel screw in the 100-count jar. There is one configuration under that number, so there is no finish or length option to specify.
5) How many screws come in a jar of Metallics JTEKDF11?
100 screws per jar. The jar pack is the stock put-up for this item, which suits a van stock or shop shelf where you are pulling a handful at a time rather than buying a bulk box for a single install.
