FST 115 Steel Iron Shafts

The FST 115 Steel Iron Shaft is lightweight and is designed to increase ball flight without sacrificing consistency and control.

  • .370" tip diameter
  • Lighter weight allows the clubmaker to use a lower center of gravity head or more head mass without increasing overall club weight

Trimming Instructions

FST 115 Steel Iron Shafts is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from Great performer for the average swing This shaft in the S/X flex is a great value and the ideal performer for the aggressive/fast swinger with a typical early hand release. And for such a player, it has great action at impact. It also launches high without ballooning to help gain a few extra yards. But because it has less than firm tip stiffness with a mid-kick point, it may feel a bit unstable at impact for the hard swinger with a Sergio Garcia-esque late hand release. But then again, that's not who it's really designed for. The FST 125 Pro would be better suited for such a swing. Also, this shaft feels a bit softer overall than the Dynamic Gold XP S300 which has a comparable bend profile.

Rated 5 out of 5 by from Great Shaft For My Longest Irons My swing speed is 103 MPH with a moderate tempo. I was playing a 4 and 5 hybrid but then I reshafted my 4 and 5 iron with the FST 115 shaft. I can hit the ball higher than with the similar Rifle shaft. The distance matches the hybrids and I love the soft, solid feel of this shaft. I am very pleased with the shaft, pricing and quality.

Rated 5 out of 5 by from Big fan of this shaft. Bought this shaft last year to replace a broken Taylormade Rocketbladez 4-iron as they don't sell the stock shaft. Once I shattered my 7-iron this year, I knew this was the shaft to buy again.

Need to replace "R" shafts in my Rocketbladez. Dispersion is hi, and these set my HC south. I have to smooth them to hit fairly well (where I get pulls too) and lose yards if I swing more aggr.. CPM 5i is 269 at 5" (??) and 5i =160 yds

Asked by: Al_B
If you have the stock steel shaft that came in the Rocketbladez irons it was listed as an 85 gram weight shaft. It would also be made by FST. The FST 115 shaft will be heavier in weight but likely not play much stiffer in flex if it is cut to an R flex. An S flex in the 115 might work better. You might also look at the True Temper Score LT (TT0100) which is similar in weight to the FST 115 but plays truer to flex compared to the FST 115. http://www.golfworks.ca/true-temper-score-lt-steel-iron-shafts/p/TT0100/

I am between R and S flex . More cut on R flex or , Less cut on S flex to have a sub-flex. ? Tanks Serge

Asked by: Serge
In the case of the FST 115 shafts you could go with either the R or S flex shafts unless you happen to have a 1 iron. If you have a 1 iron you would have to start with the R flex and trim more because the S flex calls for 0" tip trimming for the 1 iron and you cannot trim less. The specifications on these shafts is the same except for flex.

Hi: I'm looking to replace my uniflex shafts for my 2002 big berthas and want to keep a similar flex. But I want to try something lighter, 100g or so. Would these be a good shaft to try? Any Suggestions?

Asked by: Payango71
The stock Uniflex steel shaft that was listed for the 2002 Big Bertha irons weighted 120 grams. The FST 115 will be a little lighter weight but not much. The Apollo Target (AP0004) at 105 will be lighter and have similar playing characteristics as the stock Callaway shaft. http://www.golfworks.com/apollo-target-golf-shafts/p/AP0004/

i'm 70 yrs old. love to play golf. i'm loosing height on my irons. the shots are coming in to flat. the shafts are r flex. what do you recommend ?

Asked by: unclesam67
In steel shafts you might look at a lighter weight shaft like the FST 90 which can be cut to either the R flex or the A (Senior) flex. It would be a lighter weight shaft then the FST 115 which could help. You might also want to consider a graphite iron shaft. We get very good feedback from the Xcaliber (AS0023) L/A cut to the A flex. http://www.golfworks.com/fst-90-steel-iron-shafts/p/FS0011/ http://www.golfworks.com/axe-xcaliber-graphite-irons-shafts/p/AS0023/

Looking to replace grafite shafts with steel on callaway x hot irons stiff flex

Asked by: Tk57
The FST 115 steel shafts will work with the X Hot irons and could be a very good match. They are a very good inexpensive shaft. If you are looking for some other options the True Temper Score LT (TT0100) and Multi-Step (TT0061) are other very good inexpensive options.

I need a replacement shaft for 2013 Speed Blade 4 iron. The Taylor made specs call for Tip .370 and butt .600,,,,however they also call for FST 3B3H  or 4B3H..  Are these the same

Asked by: Elvis
The 3B3H and 4B3H reference a flex and playability code we assign to shafts we carry. FST, the brand, does not have a shaft with those codes. The "3" designates an R flex and the "4" designates a S flex. There a lot of options that are .370 tip and a .600 butt. If you go to The Golfworks website and in the left nav click Maltby Playability Factor, then click MPF Shaft Ratings, you will find all the shafts in our catalog that have the codes you listed. They are sorted by woods, irons, hybrids and wedges. The link is below: http://www.golfworks.com/images/art/ShaftMPF.pdf

I am 49 and own a set of Nike cast CCI irons but I am having a hard time hitting them higher now. Would you recommend this shaft for me? 

Asked by: Rayjr
The A/R combination flex of the FS0012 is a higher trajectory shaft in either the A or R flex, so it could work. If you play an S or an X flex, the FS0012 is more of a Mid trajectory shaft so it is difficult to say if you will hit it higher. Without knowing the characteristics of the shaft that is in the clubs now, it is difficult to say how much difference there might be with any choice you make, but I would definitely suggest looking for a softer, higher trajectory option.

The FST shafts are they the same as the KBS shafts. I noticed that the KBS are made by FST. Does anyone know this.

Asked by: Dadwholuvsgolf
FST is the parent company for KBS. FST (Femco Steel Technology) has been in business for a number of years.
