Frequently Asked Questions

Q: What drill or screwdriver types is this 1/4" hex flexible shaft compatible with?

A: This flexible shaft extension is designed to fit any standard hand drill chuck or power screwdriver that accepts a 1/4-inch hex shank. It works with most cordless drills, electric screwdrivers, and ratchet screwdrivers, making it highly versatile for home and professional use.

Q: How much can the flexible shaft bend without losing torque?

A: The carbon steel soft shaft is engineered to flex through tight angles — typically up to around 90° — while still transmitting consistent torque. It performs best at moderate bend angles for everyday fastening tasks; extreme sustained bends may reduce longevity over time.

Q: Which length should I choose for my project?

A: For shallow recesses and close-quarters work, the 150mm or 200mm option is ideal. The 300mm length suits medium-depth cavities such as cabinet interiors, while the 400mm shaft is best for deep or hard-to-reach spaces like wall cavities or structural framing on construction sites.

Q: Is this flexible shaft suitable for professional construction site use?

A: Yes. The carbon steel construction makes this shaft durable enough for regular use on construction sites and in trade environments. It is designed as a hand tool accessory for standard drilling and fastening applications.
