#10-24 x 2 in. Phillips Hex-Head Machine Screws (15-Pack)

When you go to Home Depot for my screws, pick up some of these.

Phillips indented hex washer head screws.

Lyn thanks for the effort. I see that you sent a picture of a machine screw. I have a feeling that you know the difference between a hi-lo screw and a machine screw and you were just trying to make a funny ( ha,ha !) .

Oh and I found the screws for your GHT 225.

Home depot has these too.

WOW, you don't screw around do you?

He was just scr... , um, messing around with you!

Same screws I need for my trimmer.

Like this one.

Why is it important to have both Phillips and a hex head, as long as it does the job? If you must have 2 ways to drive it you could use hex head and saw a slot for an ordinary screwdriver.

No, it doesn't have to be Phillips and hex, it could be hex and Allen or hex and star.

Climate technologies, the manufacturer of the Bon Aire Durango decided to use a hex and Phillips screw. I imagine that the engineering team at their company determined that this type of fastener would be best suited for the application.

The Master Cool MCP 44 is a copy of the Durango. The mcp 44 uses a hex and slotted screw combination.

I have visually analyzed both of these screws, the Phillips screw appears to have greater holding power to drive the screws into the plastic better, while the slotted screw tends to wobble about the head and it is more difficult to drive the screw into the plastic straight.

Engineers could confirm that a Phillips works better than a slotted screw mathematiclly based on pitch and thrust angles.

The screw drivers I use are Snap On, these tools are generally manufactured to a stricter tolerance than a driver purchased from a lesser known distributor.

It would appear that a Phillips/hex head combination should be as widely distributed as a slotted screw combination would be.

Another point is the molding of the coolers plastic housing. In several areas, where the screws are used, the hex head allows the installer to drive the screw almost all of the way into the mounting boss, yet the shoulder of that same mounting boss requires a Phillips driver to be used to fully seat the screw.

What you really need is some totally weirdo screw head for which you have the only tool for miles around. Then you can build up a business monopoly.

A better question would be "why do you care?" Fasteners for high speed assembly are chosen according to the process, materials, and tooling; providing both a hex head and a Phillips drive is a convenience to the person using the fastener. That said, a quick look at the head of the screw in the picture provided by Lyn, gives another reason- the forming process of the hex head provides additional bearing surface as compared to a round head, obviating the need for a washer to spread the load (a bean-counter's dream, 100,000 washers that don't need to be bought!). The extra driving means just makes it easier to use whatever tool the guy/gal driving the screw has in their possession when they're repairing the product.

nb- Plastite has the patent on the unique shape of the threads, their licensees can put whatever head they like on the fastener. Look for a company named REMINC for your specific needs.

Ram consult, thank you for the reminc link.

Some brands of stitching screws ( for sheetmetal ) have that head. At least, in Oz.

Plastite screws come in a couple of types with different thread angles. If you are fixing into a pre-formed hole you need to use the appropriate type to hold properly. Over here, the pozi/hex head is known as a universal head, sometimes has a slot as well. Don't know if it's called the same where you are.
