1. JT-87 screwdriver set, preferred choice for non-slip, smooth bearing, magnesium-silicon alloy, long-lasting magnetism
2. Model has: Hexagonal T2/Y-type 0.6/Cross 1.5/Five-star 0.8/Middle plate 2.5
3. Chaoshun Bearing: After 10,000+ times of testing, strict quality control bearings do not lag, and the duration of one rotation is up to 1 minute
4. Strong magnetic adsorption, batch head magnetism is not easy to fade without worrying about the loss of small screws will fall off
5. S2 steel based on the addition of chromium, molybdenum, tungsten, vanadium, and other alloying elements to improve the hardenability, toughness, wear resistance, and heat resistance
6. Professional non-slip design, works more easily, can increase the friction between the hand and the screwdriver
