Not the least expensive out there, but if you use your tools daily these are a bargain. They also have a lifetime warranty - no questions asked replacement. This set has a wide range of sizes, comfy handles that allow a solid grip, and both labeled and color-coded as to size for a quick grab. Review: Very pleased with this set of drivers. - They're Klein, and that typically means quality tools and this set doesn't disappoint. I keep the set in my Veto MCT bag which lives in my van and I only pull it out on big jobs. I think what sets Klein apart is the color and sizes on the handle tips, makes them easy to identify and pull from the bag. Quality is just superb and I like that the shank is hollow. Couple weeks ago was working in a cooler and had to replace a little evaporator blower fan. I grabbed the MCT bag and used this driver set because nothing else was going to make quicker work of it than these. The set offers up the majority of sizes that I'll ever run into so for me it was perfect. If your looking for a great starter set, new to the HVAC trade like I was when I purchased this is a great set to go with. Keep in mind this isn't the set with the magnetic tips, this is the hollow shank type which is very useful for removing nuts on bolts that are very long. ## Features - VERSATILE TOOL SET: Includes commonly used nut drivers for various applications - HOLLOW SHAFT DESIGN: Facilitates work on long bolts with internal flanges for a secure and twist-resistant shaft anchor - ENHANCED HANDLING: Cushion-Grip handles provide greater torque and comfort during use - EASY IDENTIFICATION: Tip-Ident color coding on handle ends quickly identifies nut driver hex orientation and size - MADE IN USA: Ensures superior quality and craftsmanship - SOLID ANCHOR: Integral flanges ensure a twist-resistant blade anchor for reliable performance - COLOR-CODED HANDLES: Allow for easy engagement with the fastener ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000BYEPS | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #57,560 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #120 in Nut Drivers | | Brand | KLEIN TOOLS | | Certification | ANSI | | Color | Non-magentic | | Customer Reviews | 4.8 4.8 out of 5 stars (1,271) | | Date First Available | January 1, 2008 | | Finish | Brushed | | Global Trade Identification Number | 00092644650154 | | Head Size | 3/16, 1/4, 5/16, 11/32, 3/8, 7/16, 1/2 inch | | Head Style | Hex | | Included Components | 630-3/16, 630-1/4, 630-5/16, 630-11/32, 630-3/8, 630-7/16, and 630-1/2. | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 1.47 pounds | | Item dimensions L x W x H | 1.5 x 7.5 x 13.5 inches | | Item model number | 631 | | Manufacturer | Klein Tools | | Material | Alloy Steel | | Measurement System | Inch | | Model Name | 631 | | Number Of Pieces | 1 | | Number of Items | 1 | | Part Number | 631 | | Pattern | Tool | | Power Source | corded-electric | | Product Dimensions | 1.5 x 7.5 x 13.5 inches | | Recommended Uses For Product | Electrical work, DIY projects, Heavy-duty tasks involving various screw sizes and materials | | Shape | Rectangular | | Size | Non-Magentic | | Special Feature | Soft Grip | | Special Features | Soft Grip | | Style | Non-Magentic | | Thickness | 1 Inches | | UPC | 092644650154 | | Usage | personal | | Warranty Description | Klein offers a lifetime warranty on material defects and workmanship for the normal life of the product. | ## Product Details - **Brand:** KLEIN TOOLS - **Color:** Non-magentic - **Head Style:** Hex - **Material:** Alloy Steel - **Number of Items:** 1 ## Images ![Klein Tools 631 Tool Set, Made in USA, Nut Driver Set w/Hex Nut Sizes 3/16, 1/4, 5/16, 11/32, 3/8, 7/16 and 1/2-Inch on 3-Inch Full Hollow Shaft, 7-Piece - Image 1](https://m.media-amazon.com/images/I/51pgbiOLXXL.jpg) ## Questions & Answers **Q: I lost the 5/16 driver from the set.

Keep in mind this isn't the set with the magnetic tips, this is the hollow shank type which is very useful for removing nuts on bolts that are very long. ### ⭐⭐⭐⭐⭐ Finally bought the entire set *by R***Y on April 7, 2012* I had previously purchased a few of these nutdrivers but not the whole set. After using them and then realizing that more and more I needed other sizes too, I decided to purchase the set. The high quality is what brought me back to these. They have a very strong magnet that will not lose it's hold. I had a hard time deciding whether to get these ones or the ones with the longer shank. I ended up settling on these because I realized that the longer ones wouldn't fit too well in the outside pockets of my toolbag, and would be sticking out too much. Didn't want to risk them falling out and losing one somewhere. Bought these and have been using them extensively ever since. As for the ones I bought before these...I gave them to my father to show him the quality and craftsmanship of these wonderful tools. These may seem to be on the pricey side, but I guarantee that you will not regret it and would purchase again if need be.
