Minerallac 77016-6 10 x 1" Self-Tapping Hex Washer Head Screws, Zinc Plated

The Minerallac 77016-6 is a 10 x 1" self-tapping sheet metal screw built for electricians, HVAC technicians, and metal fabricators who need a dependable fastener for enclosure and sheet metal assembly. Each screw features a hex washer head that combines the wide bearing surface of a washer with the fast-driving convenience of a hex head, along with a Phillips/Slotted combination drive that accepts either a Phillips or flat-blade screwdriver for flexible installation. The self-tapping thread cuts its own path into sheet metal, eliminating the need for pre-drilled or pre-tapped holes and speeding up installation in the field or at the bench. Finished with zinc plating for corrosion resistance, the 77016-6 is packaged and sold by the jar, making it easy to keep a ready supply of fasteners organized and within reach in the shop, service van, or job box.

Key Features

  • Screw Size: 10 x 1" self-tapping sheet metal screws sized for secure fastening into metal panels, enclosures, junction boxes, and electrical cabinets.
  • Hex Washer Head: The integrated hex washer head provides a wide bearing surface and can be driven with a wrench, nut driver, or screwdriver for added installation flexibility.
  • Dual Drive Design: A Phillips/Slotted combination drive accommodates either a Phillips or flat-blade screwdriver, so installers can use whatever tool is on hand.
  • Self-Tapping Thread: The self-tapping design cuts its own threads directly into sheet metal, eliminating the need for pre-tapped holes and reducing installation time.
  • Corrosion-Resistant Finish: A zinc-plated finish helps protect the screw against rust and corrosion for long-term, dependable performance.
  • Jar Packaging: Screws are supplied in a jar for organized storage and clean, easy dispensing in the shop, on the truck, or at the job site.
  • Versatile Fastening: Suited for a wide range of sheet metal and light-gauge fastening tasks where a secure, low-profile head is required.

Minerallac 77016-6 – Frequently Asked Questions

1) Do I need to pre-drill before driving the Minerallac 77016-6 sheet metal screws?
No pre-drilling or pre-tapping is needed. The 77016-6 is a Type-A self-tapping thread, so it cuts its own thread as it drives into sheet metal. Type-A is the coarse, sharp-point sheet metal thread meant for light gauge metal panels, enclosures, and duct, not for structural steel. On heavier gauge you will still want a pilot hole to keep the point from walking.
2) What driver or bit do I need for the Minerallac 77016-6 hex washer head screws?
Three options, all on the same screw. The drive is a Phillips/Slotted combo, so a #2 Phillips bit or a flat blade both seat in it, and the hex washer head takes a 5/16 inch nut driver or wrench. That is useful in an enclosure where you cannot get a drill square to the panel and have to finish by hand.
3) What size are the Minerallac 77016-6 screws, and how much material will a 1 inch screw hold?
They are a #10 x 1 inch screw, so the 1 inch is overall shank length under the head. On sheet metal work that leaves plenty of thread past two stacked panels or a bracket on an enclosure wall. If you are only fastening a single thin panel to a frame, 1 inch will stand proud on the back side, so plan for the point breaking through.
4) Will the hex washer head on these Minerallac screws cover an oversized or slotted hole?
The head measures 0.312 across and 0.340 high, with a built-in washer flange under the hex. That flat bearing surface spreads load and sits flush against the panel, so it bridges a slightly oversized hole or a slot without a separate washer. For a badly stripped hole you are better off stepping up a diameter than relying on the flange.
5) Are the Minerallac 77016-6 screws OK for a damp or outdoor enclosure?
The screws are hardened steel with a zinc plating, which handles indoor humidity, shop air, and occasional moisture in a panel or duct run. Zinc plating is a general corrosion-resistant finish, not a marine or constant-wet coating, so for coastal exposure or a washdown area specify stainless instead.
6) Can I use the 77016-6 screws for HVAC duct as well as electrical panels?
Yes. Same screw does both. Electricians use it for enclosure and junction box assembly, conduit strap and bracket mounting, and sheet metal cabinets; HVAC techs use it for light-gauge duct and plenum fastening. The low hex washer head keeps the profile down so it does not foul insulation or a panel door.
7) How are these Minerallac self-tapping screws packaged for a service van?
Sold by the jar, which is the point of them for a truck or job box: screws stay contained and you can pour out a handful at the panel instead of fishing through a bulk box. One jar covers a lot of enclosure and bracket work.
8) Where are Minerallac 77016-6 screws made, and what is the manufacturer part number to reorder?
Order by Minerallac part number 77016-6, the #10 x 1 inch zinc-plated hex washer head self-tapper. Country of origin is Taiwan. Distributors matching this against a cross-reference should note the Type-A thread and Phillips/Slotted combo drive, which distinguish it from the Phillips-only hex head variants in the same size.
