Screw Capricorne 90MF is an Attack-Type Beyblade that appears in the anime and manga series, Beyblade: Metal Masters. It is owned by Dr. Ziggurat and is part of the Maximum Series. It was released on January 22, 2011 in Japan.

Face Bolt: Capricorne

The Face Bolt depicts "Capricornus" (also known as Capricorn), one of the 88 constellations in space. Capricornus is Latin for "horned male goat" or "goat horn" and is represented by the "sea-goat", a mythical creature that is half goat, half shark. The design is a yellow outline of a goat's face on a purple Face Bolt.

Energy Ring: Capricorne

Capricorne is a fluorescent blue in color featuring horns of a goat.

Fusion Wheel: Screw

Screw has three distorted wing-like forms, each with an upward curved spike. It was said to have the best Upper Attack of any Fusion Wheel. It is one of the best non-4D attack wheel with lots of Stamina due to something with airflow as shown on the box package. If paired with the right Track/Clear Wheel, it can provide extremely-effective Attack power.

Spin Track: 90

90 is the second shortest Track currently available, outclassed only by 85. It does have problems with floor scrapes but is useful in Attack-Type Customizations.

Attack-Type Customization

90 is a great Spin Track in Attack combos like MF Lightning/Meteo L-Drago 90RF/R2F/MF and MF Vulcan Holeseus/Zurafa/Byxis 90RF/R2F/MF.

Stamina-Type Customization

90 can also be used in Stamina combos like Burn Kerbecs/Aquario/Bull 90WD/SD/D or Earth Kerbecs/Aquario/Bull 90WD/SD/D.

Performance Tip: MF (Metal Flat)

Metal Flat has a Flat Tip made of Metal, giving it an offensive movement. However, since Metal has more friction than plastic Flat Tips it has more Defense and speed, However, unlike XF, R2F(new) and WF it can keep the sliding shoot's pattern. It is really powerful in the combo: MF-H Gravity Perseus (Left Spin, Counter Mode) D125/T125/CH120MF. It is one of the best non-4D Attack type Bottoms.
