Unlike JIS, the ISO 4757 standard for cross-head screws does not specify a dot on the screw head. [33] Phillips II [ edit ] In addition to screw drives, various nut drives have been designed to make removal difficult without specialized tools. Proprietary examples include T-Groove, Slot-Lok, Pentagon, Tork-Nut, T-Slope and Spanner designs. [69] Breakaway head [ edit ] This drive type has the disadvantage of not being as precisely controlled as can be obtained by proper use of a torque wrench; applications may still fail due to either too little torque being applied to correctly fasten the joint, or too much torque being required to shear the head, resulting in damage to the material being fastened.

A correctly sized JIS driver will engage at full depth into a Phillips or Pozidriv head screw slightly loosely, but without damage. JIS heads are often identified by a single dot or an "X" to one side of the cross slot. [30]

Needs loginSlot screw drives have a single horizontal indentation (the slot) in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make because it can just be sawed or filed. Additionally, it is unique because the slot head is straightforward to manufacture, and because it can be driven by a simple handtool. The slotted screw is commonly found in existing products and installations, along with use in simple carpentry work and in applications where minimal torque is needed. Slot screws are also used in the restoration of antique furniture, vehicles, and equipment. Line Head and Line Recess screw drives are Japanese systems with male, female and tamper-resistant configurations. [72]

Archived from the original on 2015-09-26 . Retrieved 2015-09-25.A thumbscrew is a type of screw drive with either a tall head and ridged or knurled sides, or a key-like flat-sided vertical head. They are intended to be tightened and loosened by hand, and are usually not found in structural applications. They are sometimes also cut for Phillips head or slotted screwdrivers, as well as having the knurling for finger grip. ASME Standard 18.6.8 covers dimensions for Type A (shoulder under the head), regular and heavy, along with Type B (without shoulder), regular and heavy. They can be found on many computer cases, and in other locations where easy access without tools is desired. 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] ASTER System". www.lisi-aerospace.com (in French). Archived from the original on 2018-06-13 .
