Review: Sturdy Alternative to Undersized Precision Screwdrivers - The Torque We've Been Waiting For. - Overall Length: 7 3/4" (200mm) Shank Length: 4" (100mm) Tip Width: 1/8" (3.2mm) MAIN ADVANTAGE: A small tip width, with a larger diameter handle than most 1/8" tip screwdrivers...Klein's miniature series included, this link was previously the best Klein screwdriver with a 1/8" tip, but note the small handle diameter Klein Tool 608-4 1/8-Inch Cabinet Tip Miniature Screwdriver with 4-Inch Round Shank MAIN DISADVANTAGE: The temptation to use it on things other than low torque wire terminating, which will likely result in a broken tip. Just because you see that reliable black and yellow sticking out of the dark recesses of your tool bag, don't give in to temptation and begin to use this on any other type of screw other than a terminal block. THIS TOOL FITS 99% of the terminal blocks in our facility. I found one type that had a just under 3mm screw hole width (screwdriver tip is 3mm wide), which made me have to pull out the old precision screwdriver. But, they are fairly rare and you can count on this fitting most standard IEC and NEMA blocks. The truth is I could have forced this tool down into the hole and probably tightened the screw, but that leads to other problems with distorting the terminal block and causing the tightening screw to move over and disappear. IT SEEMS UNIMAGINABLE that a Klein screwdriver (other than one that uses 10 different bits) would get any other rating other than 5 stars. This one is no different. I have searched feverishly for a high quality regular screwdriver that will work on terminal blocks. I have been struggling with different sets of precision screwdrivers for years trying to find one that will produce the proper torque, fit in the screw properly and last (many broken undersized tips in my past). LOOSE TERMINAL BLOCK SCREWS in an industrial facility are producing downtime at an ever increasing rate, as things get more automated. I believe they are so common because few technicians (me included) own a screwdriver that will tighten the screw properly. Especially if there are more than one wires under the same terminal block screw. Control panels/terminal blocks are the central nervous system of the facility. Now you can give them the attention they deserve and put that "precision" screwdriver to work tightening your sunglasses, not critical controls terminations. Review: Nice fit and provide that extra torque when needed. - Good screwdriver. This is great for tightening Phoenix terminal and other small terminal. A must have for panel builders ## Features - PRECISION-MACHINED TIP: Screwdriver contains a precision machined tip to reduce cam-out and provide exact fit for terminal block screws - 1/8-INCH CABINET TIP: 1/8-inch (3.2 mm) tip is up to 19-Percent stronger than competitors - HIGHER TORQUE: Tip achieves 76-Percent higher torque value than the required ASME B107 Standard - CUSHION-GRIP HANDLE: Provides greater torque and comfort for consistent and continual driving - MADE IN USA: Manufactured and assembled in USA for quality and performance - CHROME-PLATED BLADE: Heat-treated and chrome-plated blade provides corrosion resistance and added durability throughout the life of the tool - DOUBLE-FLANGE BLADE: Anchor inside handle to provide solid, twist-resistant connection for greater torque ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0058I6VNE | | Best Sellers Rank | #15,135 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #68 in Screwdrivers | | Brand | KLEIN TOOLS | | Brand Name | KLEIN TOOLS | | Color | Black | | Customer Reviews | 4.8 out of 5 stars 2,289 Reviews | | Global Trade Identification Number | 00092644322266 | | Head Size | 1/8 inch | | Head Style | Flat | | Included Components | Tools & Accessories | | Item Dimensions | 7.75 inches | | Item Type Name | Klein Tools 612-4 Screwdriver, Flat Head Terminal Block Screwdriver, 1/8-Inch Cabinet Tip, 4-Inch Round Shank | | Item Weight | 2.4 ounces | | Manufacturer | Klein Tools | | Manufacturer Part Number | 612-4 | | Manufacturer Warranty Description | 1 year manufacturer | | Material | Alloy Steel | | Material Type | Alloy Steel | | Model Name | 612-4 | | Model Number | 612-4 | | Number of Items | 1 | | Recommended Uses For Product | Electric Appliances | | Special Feature | Cushion Grip | | UPC | 092644322266 | | Unit Count | 1 Count | ## Product Details - **Brand:** KLEIN TOOLS - **Color:** Black - **Head Style:** Flat - **Material:** Alloy Steel - **Number of Items:** 1 ## Images ![Klein Tools 612-4 Screwdriver, Made in USA, Flat Head Terminal Block Screwdriver, 1/8-Inch Cabinet Tip, 4-Inch Round Shank, TB-DIN - Image 1](https://m.media-amazon.com/images/I/51APfPlk95L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Is this correct suze for receptacle plate covers on a outlet?** A: It’s too narrow. A 3/16” tip makes it a little easier not to scratch a new stainless plate cover, but a 1/4” tip will also work as long as the tip isn’t off center of the screw. **Q: Please what is the right size, the description says it is 1x1x1 it is impossible** A: Cushion Grip Tip Type: Cabinet Magnetic: No Tip Size: 1/8'' (3.2 mm) Shank Type: Round Shank Length: 4'' (10.2 cm) Material: Steel Insulated: No Handle Color: Black Overall Length: 7.75'' (19.7 cm) Weight: 2.4 oz (68 g) **Q: Will it fit in your brest pocket?** A: It will fit. But its probably a little bigger than you would want to carry in your shirt pocket. **Q: Is the head small enough to adjust sprinkler heads?** A: Yes I have used it in my Rain Bird nozzle heads. Usually I use it for Phoenix connectors in home theater and home automation though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Sturdy Alternative to Undersized Precision Screwdrivers - The Torque We've Been Waiting For. *by J***D on September 5, 2011* Overall Length: 7 3/4" (200mm) Shank Length: 4" (100mm) Tip Width: 1/8" (3.2mm) MAIN ADVANTAGE: A small tip width, with a larger diameter handle than most 1/8" tip screwdrivers...Klein's miniature series included, this link was previously the best Klein screwdriver with a 1/8" tip, but note the small handle diameter Klein Tool 608-4 1/8-Inch Cabinet Tip Miniature Screwdriver with 4-Inch Round Shank MAIN DISADVANTAGE: The temptation to use it on things other than low torque wire terminating, which will likely result in a broken tip.
