Frequently Asked Questions

Are these wrenches suitable for stainless steel fasteners?

Yes, the 12-point design provides a tight grip without rounding corners, making them safe for use on stainless steel fasteners common in marine environments.

What does 12-point ratchet mean?

A 12-point wrench has a box end with 12 notches, allowing it to engage the fastener every 30 degrees. This enables use in tight spaces without fully rotating the wrench, while the ratchet mechanism further reduces the swing angle.

Do these wrenches come in imperial sizes?

The standard product range is metric, but imperial sizes may be available upon request for specific ship chandler orders. Please contact us for special requirements.

Are the heads reversible?

Yes, each head has a simple reversing lever or mechanism that allows the ratchet to operate in both clockwise and counterclockwise directions.
