## Description

OTC's 52-piece Master Torx Professional Socket Bit Set features a sturdy, blow-molded case and popular versions of Torx specialty fasteners in all common sizes. Ideal for many automotive applications like: seat belt bolts, interior and exterior trim screws, engine assemblies, tail lamp lenses, bumpers, headlight bezels, door strikers and latches, and much more.

Whether it’s a specialty tool or unique piece of service equipment, OTC provides top solutions to modern automotive service challenges while increasing technicians’ productivity and shop profits.

Review: Quality - Good quality and added ssizes are a plus
Review: Looks like an excellent set, but E-Torx sockets have extreme bevels not suited to short-headed bolts - This is one of those fairly useless reviews, where I just bought the set and have little experience with it. But like the OTC tools I've had before, this seems to be of good quality that should hold up under commercial use and last a DIYer forever, abuse excepted. My primary reason for writing an early review is to comment on the extremely deep bevel of the inverted Torx sockets in this set. My experience with E-Torx is fairly limited, and I only owned a small import set of E-Torx sockets prior to this purchase. They have a slight bevel, but these OTCs are extreme to my eye. I had hoped to use the E20 to remove Nissan flywheel bolts, which do have short heads, but the E20 in this set will only chew the tips off of the flutes. If such a situation is a concern for you, take note. I'll keep the set, though, because it is comprehensive and undoubtedly better quality than any of the others I have. As others have noted, these tools are unfinished steel, neither plated nor black oxide.

## Questions & Answers

**Q: I'm comparing 2 sets: this otc #5900a 52pc set for $84 vs neiko #10083a 60 pc set for $61. Any thoughts for diyer? Is OTC worth more $ for less parts?**
A: Neiko has chromed sockets, looks like OTC has black oxide, Neiko has the E11, T-7 and T-9 which are missing from the OTC set and 5 tamper bits are also missing.  Tough decision, both are made in Taiwan.

**Q: What sizes are these 1/4 , 3/8, 1/2 inch?? Why is that not included in your description**
A: It's a mix of all of them. The smaller sizes are in 1/4, medium sizes in 3/8 and I'm pretty sure there are some in 1/2 as well......I don't have the set in front of me right now.

**Q: Does the set include a T57?**
A: No, it doesn't. Sorry

**Q: What's the lead time on these?Does it really take 1 to 2 months to ship?**
A: 1-2 months to ship is possible. I have customers that have been told they should not expect some of their stuff until 2024.

### ⭐⭐⭐⭐⭐ Good for the money.
*by B***K on March 12, 2012*

I got this OTC set because it covers *most* everything you are likely to encounter. The only torx style it is missing is the Torx Plus Tamper proof which is a five point that is different from all other torx that are six point. You add OTC set 5905 to cover them then you have every type of torx socket there is. Then... you add XZN sockets (triple square) such as the VIM Tools VIMXZNS1000 for the German vehicles. Then get you a metric and standard set of hex (Allen) sockets you are set for everything. The quality is good. I have not damaged any sockets yet. Edit: When writing this review I forgot about 'Ribe" whose use is very limited (Euro,) there is also external torx plus (EP) that is even more rare (GM/Chevy truck seat bolts) but is starting to spill over into other uses. Just when you thought you were done buying tools.... *Update* Another Torx style has been released since this review, Torx EPR which is an external 5 point. Then there is Mortorq which is a 4 point twisted bit. Then you need to deal with the 3, 5 and 10 point fasteners on the Euro builds. Also I ran into a "MS" fastener on a newer Nissan. You'll never be done buying tools...
