Metallics JTEKDF4 – Frequently Asked Questions
1) Do I need to pre-drill before installing the JTEKDF4 screw?
No. The JTEKDF4 is a self-drilling (SD) screw, so the point cuts its own hole in sheet metal as it drives. One pass with a #2 Phillips bit, no pilot hole step.
2) What part number do I order for the Metallics #10 x 1/2 self-drilling flat head screw?
Order Metallics JTEKDF4. That single part number covers the #10 x 1/2 inch Phillips flat head self-drilling screw in steel with zinc finish, supplied in a jar of 100. There are no finish or size options to specify with it.
3) How many screws come in a jar of Metallics JTEKDF4?
They ship 100 to a jar. The jar pack is how Metallics supplies this #10 x 1/2 inch self-drilling screw, so a single order quantity gets you a hundred pieces for panel and strap work rather than a bulk box.
4) Will a flat head self-drilling screw sit flush, or does it need a countersunk hole?
A flat head seats flush only in a countersunk or dimpled hole. On flat sheet steel the JTEKDF4's head will stand slightly proud unless the hole is countersunk. If you need a flush look without countersinking, a pan or wafer head is the better choice.
5) Is the JTEKDF4 screw suitable for outdoor or damp locations?
It's zinc plated steel, which is intended for dry interior use. Zinc plating gives limited corrosion protection and is not a substitute for stainless or hot-dip galvanized hardware in wet, exterior, or corrosive environments.
6) What is the JTEKDF4 screw typically used for on an electrical job?
It's an electrical-trade fastener, a #10 x 1/2 inch self-drilling screw for attaching to sheet metal: enclosure covers and panels, strut and strap mounting, device and box hardware, duct and raceway supports. The 1/2 inch length is short, so it is for thin-gauge metal attachment rather than anything needing deep thread engagement.
