I am working on the last couple pieces of my recovery gear and I have question for those that are knowledgeable about metal. I need a 10,000lb WLL, and a 20,000LB WLL shackle and I plan to pick up a pair of Crosby shackles. The question I have is they have two versions the G-209 and G-209A, A meaning alloy. The alloy shackle has a higher WLL based on equivalent size, and they are also cheaper. Other than the size are you giving up anything by going with the alloy shackles?
When talking about metallurgy, an "alloy" is simply a metallic material that is comprised of multiple base metals. A common example of an alloy would be steel. This means that there is no answer to the question "am I giving up anything up by going with the alloy shackles" unless we know two things:
1. What specific alloy is used in the G-209A shackle?
2. For comparison, what material is the G-209 shackle made of?
1. What specific alloy is used in the G-209A shackle?
2. For comparison, what material is the G-209 shackle made of?
I'm not sure what the specific composition of either shackle is. Links to the spec sheets are below, but it my research I either haven't seen it, or dont know enough about metal to know that I have seen it. Both appear to meet the same testing standards, I just cant figure out why someone would spend more on a larger shackle with a lower WLL unless size what main determining factor.
Crosby® 209 Carbon Screw Pin Anchor Shackles - The Crosby Group
Crosby® 209A Alloy Screw Pin Anchor Shackles - The Crosby Group
You asked specifically about someone who is "knowledgable about metal", so that's the kind of answer I gave, lol. I'm no metallurgist, but I have some formal material science education, pretty much just enough to be dangerous.
They adhere to similar testing standards yet the 209 is rated "grade 6" while the 209A is rated "grade 8". The ASME B30.26 standard is a rigging standard. For more info, go here:

In short, it looks like the "alloy" used for the 209A is stronger than whatever material is used for the D in the 209 shackles, with the exception of the pin, as both the 209 and 209A have an alloy pin. Either would be fine and you're not "giving up" anything by going with the alloy shackles. If anything, you're gaining strength with the alloy shackles.

Thanks, thats what I got out of it, but its nice to have another set of eyes sometimes. I was into the import scene as a kid so everything related to off road equipment and driving is seeing it for the first time. Appreciate the help.

There sure are quite a few Bright Bulbs in ONSC! I have zero knowledge of what you just spoke to Johnny C.! @Rice is a Physics teacher and I believe @jamesurq graduated from MIT???
I will just go ahead and lay claim to being a mental midget.....like my avatar would say..."I'm not a smart man, but i know what love is....."

I got an executive supply chain certificate at MIT. I wish I had an actual degree from them
Looks good on my Linked In though doesn't it?

I got a T-shirt from MIT so NC let's me teach physics.
Well the guy with the LS400 never got back to me and all the other's i've seen are overpriced..... meaning they are nice but someone wants over 10k for a 20 year old car or they are beat up and crap and someone still wants too much for them. I've switched my gaze to the GS class.... and am contemplating a early 2000 S class benz since that is just about my dream commuter car but it will be more of a headache than a lexus and this is really Andrea's car so i've kind of ruled them out.
Anyway i'll be looking at this GS tomorrow for 4k
After we get the new car sorted and the jetta sold i'll use the money from the jetta for my engine build up on the Burban.

@JToobe don't sell yourself short. I have been a builder, designed and built houses and commercial, worked as an Architect (plans stamped by structural engineer I contracted) designed and built radio controlled helicopter equipment now I build trucks. Two years of college, heading to Lafayette but hated it. No formal degree.
Education comes in many forms. My father in law was a material and scheduling "engineer" in the nuke industry for years. He was sought after all over the country. No degree, he was the only one.
I have know a great many engineers, very few could translate what was in their head much past a drawing. @Rice is a rarity, all those brains and they actually talk to his hands

Andrea's mom has one and I did consider them but for some reason they fetch a higher price than the lexus equivalent the ES.... I guess people get scared of "lexus" prices on repairs so they depreciate faster.
I'd be happier with the larger LS..... an LS460 may be in my future in a few years if I decide to not play roulette with the benz, but the GS is respectable. The GS430 will do 0-60 in 5.7 and the quarter in 14.1 so I won't say its a fast car and will be the 2nd slowest V8 car i've owned but it is quick and still will return 26-28 mpg highway from all the thread's i've seen on clublexus.com
We will be putting about 90 miles a day on it but lexus reliability is up to the task in my book and Andrea does get paid miles for driving from her different centers she is over and also mileage too work on fridays (lots of people don't work in the city on fridays) so I think it will work out for us for now.

Thanks NCFJ.....I know I'm a tremendous slouch! And like Ty Webb, I measure myself against others by height and since I'm 6'4", I usually feel pretty good about myself! I agree with you 100% and think we put too much value on formal education! I wish I was more mechanically inclined but it's just NOT my sweet spot.....being relational with the spiritual gift of sarcasm has been my bent.....I do possess a few skills: have piloted both an airplane and a helicopter but i haven't flown in 24+ years.@JToobe don't sell yourself short.

Cool, I was fortunate enough to fly both as well, last time in a small plane was 9 years ago. I was fortunate to get hands on with a Jet Ranger when I was at an RC heli meet in TX, wow 25 years ago. REal heli was actually easier than the RC, but all I was doing was pedals and sticks, pilot told me where to keep the throttle control and watched gauges etc.

90% of my helicopter time is in the OH-58/Bell Jet Ranger...mostly D model which was also later called Kiowa Warrior. They were not widely armed in the late 80's when they were first introduced, only for the small group of crusty Warrant Officers flying them off Oil Rigs in the Persian Gulf at night blowing up Iranian gun boats that thought they were invincible!
My wife still reminds me that only she has flown a blimp in our house.....when she worked at Turner Sports in the early 90's in Atlanta!

I know someone who might do the work for you, but it would not be complimentary.
That's fine. Send over their information.
