Hex Socket

how do i unscrew a rounded hex nut?

our hot water heater is leaking from the anode rod. we took the safety precautions. and went to take the anode off…we used a 12 point socket instead of 6. it rounded the hex nut. so any suggestions on what to use to get it off?

They make special sockets for this purpose. Instead of having points, they spiral to grab the nut, even if it is round. The Craftsman ones from Sears sometimes will do the job, but personally, I would spend the extra money and get it from Snap-On. Cost a lot more, but much more likely to do the job. Even the Snap-On one is cheaper than a plumber.

As tight as it probably is, something like vise grips or any kind of wrench would not help.

GAO Tek Inc. Rolls Out Upgrades for VP28B+ and VP38B+ Universal Programmer – VP280 and VP380

GAO Tek Inc. is introducing upgrades to its VP28B+ and VP38B+ Universal Programmers. The newly developed models, VP280 and VP380, support more than 6000 and 8000 devices respectively – up to 2000 more devices than before. The new VP280 and VP380 models are capable of handling different devices such as various Programmable Read-Only Memory (PROM), Programmable Logic Device (PLD), flash microcontrollers, serial and parallel memory. They are also designed for IC testing, including TTL 74 series, CMOS Logic IC, DRAM and SRAM memory devices.

These programmers include a 48-pin ZIF socket & support 8-pin to 48-pin DIP package device. With an adapter, they are able to support from 6 pin to 208 pin device packages like PLCC, SOIC, TSOP, PSOP, BGA, and QFP. VP280 and VP380 provide IC card socket and parallel or USB ports that are dependent on the programmer. In addition, the systems can be updated through software. GAO’s USB Universal Programmer series support from 4000+ to 22000+ devices to meet your different needs for device programming or IC testing. Please visit www.gaotek.com for the lists of supporting devices for our universal programmers to find the one that best matches the chip you want and the adapter you need.
