Square STM-90 Tamiya TRF421 Alu-Titanium Screw Set S-Flex Sakaguchinetshop Special

• 42% weightsavings compared to steel-screws, even 65% savings with aluminum screws
• Material: high durable Titanium
• M3 ISO Thread with 2mm Hex-Head
• Sakaguchinetshop special: S-Flex screws are used on bottom side. They have more flex and thus provide more forvigingness on the track. On the other hand they are more soft and less durable! I am using those S-Flex screws since 2022 and am fully convinced about them.
• I suggest using a high-quality hex-wrench (e.g. Hudy, Tamiya, Arrowmax, MuchMore, ...)
• Contents of this Set:

• Titan (S-Flex):

With this set you will have weight savings of 28.9g (= 121 screws)

Attention: Due to the fact, that the S-Flex CS screws are having a smaller head at heavy crashes it might happen, that the lowerdeck will take damage. Therefore I recommend to use 8 pcs. of regular STR-306 screws at the lower arm mounts.
