Also known as an ECX or Combination Tip drive. A combined slotted and Robertson drive screw found in electrical power equipment and distribution equipment. The design allows for higher torque application with reduced camming, slipping out and damaging the fastener. [63] The ECX drive is not compatible with older combination Phillips and slotted head screws. [64] Although Milwaukee Electric Tool holds the trade name ECX, their marketing materials do not tell what type of screw head ECX is designed to fit. [50] Clutch [ edit ] Wilder, George.

UPDATE: after finally finding a proper Y000 driver at a local electronics store I was able to complete a repair on an Apple Watch series 3. While I did have some success filing down a cheap tri-wing driver until it fit the screws, there was one screw that it wouldn't loosen. The bottom line is this:

The polydrive screw drive, also known as RIBE, [74] is spline-shaped with rounded ends in the fastener head. The tool has six flat teeth at equal spacing; the sizes are determined by the diameter of the star points. Its primary advantage over older screw drives is that it resists cam out. It is used primarily in the automotive industry in high-torque applications, such as brakes and driveshafts. Handle, generally wooden or plastic handles, are fixed to the screwdrivers. To save the wooden handle from being broken, an iron is fixed to the handle.#2. Shank The Pozidriv, sometimes incorrectly spelled "Pozidrive", is an improved version of the Phillips screw drive. It is designated "Type IA" by ANSI standards. [20] and "Type Z" in ISO documents. The Pozidriv was patented by GKN Screws and Fasteners in 1962. [21] [22] It was designed to allow more torque to be applied and greater engagement than Phillips drives. As a result, the Pozidriv is less likely to cam out. [10] [23] [24] It is similar to, and compatible with, the Supadriv screw drive. [25] Improvements in or relating to screw threaded fasteners and drivers for use therewith".

This is one of those things that requires a little bit of money to be spent because the tool manufacturing process and material used both need to be top-notch.A Phillips screw head is slightly different from a PoziDriv; [10] see §Pozidriv section below for details. Spline drives were specified for 5, 6.3, 8, 10, 12, 14, 16, and 20mm size screws. [82] Its primary advantage is its ability to resist cam out, so it is used in high-torque applications, such as tamper-proof lug nuts, cylinder head bolts, and other engine bolts. Powered Screwdriver: This screwdriver is powered by electricity or a battery. Power drills with flat or Phillip’s heads are frequently used along with multi-bit screwdrivers. The Ultra-Lok, and Ultra-Lok II are some of these designs that use custom keyed drivers, which tend to be confined to industrial and institutional uses that are unavailable to the average layperson. Key-Rex screws are another design, and are used in such things as ballot boxes and bank vaults. [41] JIS B 1012-1985 ねじ用十字穴 Cross Recesses for Screws". Archived from the original on 2023-03-22 .

Similar to flathead screwdrivers, there are a wide range of sizes and lengths for Phillips screwdrivers and they also come in both manually driven and electric options. While Phillips screwdrivers do provide better control and driving power, the tip can still slip out of the screw head if it is driven with too much force. Go slow to ensure that the screwdriver tip grips the screw properly to avoid stripping the screw head. Tri-point Y000 Screwdriver (for Apple Watch and iPhone 7)". iFixit.

When the rechargeable battery is no longer serviceable, the toothbrush case may be opened by removing this screw, allowing access to the battery and motor units for recycling. The wall adapter has a molded screwdriver on its case to facilitate this. A cross or double-slot screw drive has two slots, oriented perpendicular to each other, in the fastener head; a slotted screwdriver is still used to drive just one of the slots. This type is usually found in cheaply-made roofing bolts and the like, where a thread of 5mm (0.20in) or above has a large flattened pan head. The advantage is that they provide some measure of redundancy: should one slot be deformed in service, the second may still be used.

I assume you were confused between a screwdriver and a screw drive, though? Just keep reading, and all of your confusion will be resolved. The purpose of a screwdriver is to both insert and remove screws and nuts. If you want to replace a watch’s battery, you won’t use the same screwdriver you use to hang a shelf on a wall. The different functional screwdriver design types are described below. The Recex drive system claims it offers the combined non-slip convenience of a Robertson drive during production assembly and Phillips for after market serviceability. The Phillips Screw Company offers both Phillips and Pozidriv combo heads with Robertson. [ citation needed] Slotted/Torx [ edit ]
