Choose & use with care
Compare the tool’s intended task and material with your project. Use only the load, torque or application limits stated for the specific item.
Check measurement system, bit profile, drive size and fit where relevant. Different sizes within a tool family are configuration options, not an assurance of universal compatibility.
Read the parts list for the selected set. Keep supplied cases and accessories organized and follow the manufacturer’s safe-use instructions.
Follow the instructions supplied for the exact product. Features, limits and care directions are specific to the selected model.
Order preparation takes 1–3 business days, followed by 3–4 business days in transit: 4–7 business days in total. Standard shipping is free to the contiguous United States and DC, with no minimum order.
Request a return within 30 calendar days after delivery. We pay return shipping. After receipt, inspection and initiation of an approved refund take 5–7 business days.
Before you decide
Compare the stated drive size, bit profile and measurement with the item you are using it with. Do not rely on a similar-looking photograph.
Use the listing’s included-parts information and selected configuration. Where a detail is not provided, ask us before ordering rather than assuming an accessory is included.
Use the options and measurements on the exact product page. Photographs can look different across screens; available choices are limited to the options actually shown for that item.
Check the selected product’s description and included-parts information. Accessories pictured in a use scene are included only when the listing says so.
