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.

Features:
  • .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.

whats the difference between the fst 115 and the fst pro 115? and would these fit cobra f6 irons?

Asked by: james
The FST 115 (FS0012) and the FST 115 Pro Stepless (FS0013) is a stepless shaft. They have the same playing characteristics but the stepless one for some players will dampen some of the feel that the stepped shaft has.

Hi I have the cobra f6 irons. Would these fit and would these feel some what similar to the shafts on the f6?

Asked by: James
Yes these will fit the F6 irons and should match well to the stock steel shaft in these irons. The stock steel shafts were manufactured by FST and weighted 110 grams.

I have a set of titalist with ms 209 stiff shafts , are these .370 & would they play similar ? Thanks

Asked by: Sfrey
The Titleist irons use .355" taper tip iron shafts. The FST shafts will not fit. The FST shafts test and play more flexible then normal and would hit the ball higher then the MS 209 shafts.

I have a set of 80s , titelist dci black irons , is the fst 115 gonna play & feel similar 

Asked by: Shane
The FST 115 shafts will not fit the Titleist DCI Black irons. The DCI black irons use a .355" taper tip shaft and the FST 115 shafts are only available in a .370" parallel tip shaft, which is to large to fit these irons. If your DCI Black irons had the Tri-Spec stock shaft the FST would be more flexible, even in the same flex, and would create a little higher ball flight. A shaft like the True Temper XP115 (TT0112) would play and weight similar to the Tri-Spec shafts. TT Lite XL (2XLI) would have been used as a replacement shaft back when these irons were popular.

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/
