The chrome finish is great, the thick handles fit good in the hand, and roll up pouch is actually nice. I also bought all of the individual wrenches that are not included in this set.

PERFECT set of wrenches ……. Many people who bought similar sets off trucks wish and DO buy these Double Box End Wrench Sets

Ordered this a couple weeks ago and they’ve earned their spot all ready. The build quality and chrome look and feel great in hand. They slip perfectly into tight spaces but hold on to nut and bolts tightly. The price is right. They’ve saved me a fair amount of time and hassle just by having them in hand.

This paper reviews the processing, properties, and structure of carbon fibers. Carbon fibers are derived from several precursors, with polyacrylonitrile being the predominant precursor used today. Carbon fibers have high strength (3–7 GPa), high modulus (200–500 GPa), compressive strength (1–3 GPa), shear modulus (10–15 GPa), and low density (1.75–2.00 g/cm3). Carbon fibers made from pitch can have modulus, thermal, and electrical conductivities as high as 900 GPa, 1,000 W/mK, and 106 S/m, respectively. These fibers have become a dominant material in the aerospace industry and their use in the automotive and other industries is growing as their cost continues to come down.

The length and versatility of these wrenches has proved crucial multiple times. They arent an every day ise set for me, but have been more than reliable in those “oh…poop” situations, especially inside of framerails and inside doghouse/engine compartments of semi trucks. 10mm, 8mm, 15 and 17mm have been my most used sizes on these. Definitly have to love the good thick and wide beam provided on these wrenches for durability and gripability.

I received these for my birthday. For the price Capri charges for these compared to the tool trucks I think these are well worth it. Don’t hesitate to pick these up.

Great wrenches. I used them the day I got them and haven’t put them down since. Will definitely be getting the SAE set shortly. Capri seems to be a great company to buy from, really fast shipping and they contacted me when I received them to make sure I was happy.

The wrenches are constructed with premium Chrome Molybdenum steel to provide exceptional strength and durability. Finished with our flawless MaxChrome plating, achieved by thorough polishing and careful application of chrome protective plating, it ensures durability and corrosion resistance.

The Capri Tools 0 Degree Offset Extra Long Double Box End Wrenches are designed to let you easily tackle recessed bolts and bolts in tight spots. The thin-walled super thin box end with deep profile grabs firmly onto recessed bolts. 0 degree offset allows for a secure fit onto fasteners, giving your higher torque and easier swing. Extra long handles, up to 2x longer than standard wrenches, give you more leverage. The wrenches are constructed with premium Chrome Molybdenum steel to provide exceptional strength and durability. These box ends have 12-point WaveDrive which transfers torque uniformly and prevents damaging and rounding of the bolt. Finished with our flawless chrome plating, achieved by thorough polishing and careful application of chrome protective plating, it ensures durability and corrosion resistance. Large stamped sizing won’t fade over time. Sets completes with a heavy duty canvas pouch. Wrenches are backed by a lifetime warranty.
