A 17mm socket measures about 0.669 inches across flats. That puts it between two common SAE sizes:

• 5/8 inch (0.625 in) — slightly smaller
• 11/16 inch (0.6875 in) — slightly larger

While those sizes seem close, they aren’t interchangeable. Using an almost-fit socket can feel snug at first but may slip under load and increase wear on the fastener. For the best grip, choose the exact metric size listed on the bolt head. On Walmart product pages, you can check the socket’s size, drive (3/8 in or 1/2 in), depth, and point count to match your task.

They’re close, but not the same. Here’s the comparison:

• 17mm ≈ 0.669 in
• 11/16 in = 0.6875 in ≈ 17.46 mm

That’s roughly a 0.46 mm difference, which can matter under torque. A 11/16-inch socket on a 17mm fastener may feel loose and can slip more easily, especially on worn or tight bolts. For best results, stick with the exact 17mm size. When shopping, look for “17mm” in the product title and confirm details like 6-point vs. 12-point and shallow vs. deep to suit your clearance and grip needs.

They’re not close in size:

• 17mm ≈ 0.669 in
• 3/4 in = 0.750 in ≈ 19.05 mm

Because 3/4 inch is much larger than 17mm, a 3/4-inch socket won’t grip a 17mm fastener effectively and may slip. If you’re working across metric and SAE, it helps to keep a conversion chart handy, but using the exact marked size is typically the safest approach. On Walmart, filter by metric size (17mm) and choose the right drive size and impact rating if you plan to use power tools.

Both 3/8-inch and 1/2-inch drives are common for 17mm sockets. The better choice usually depends on torque and clearance:

• 3/8-inch drive: Handy for general automotive and household tasks where space is tight and torque is moderate.
• 1/2-inch drive: Useful when you need more leverage for higher-torque jobs or stubborn fasteners.
• 1/4-inch drive: Typically too small for most 17mm applications.

Also consider shallow vs. deep (for stud length or recessed bolts) and whether you need impact-rated sockets for power tools. Checking these specs on the product page can help you match your tool setup.

It depends on your job and tool access:

• 6-point: Generally offers a more secure bite on the flats, which can help reduce slipping on high-torque or slightly rounded fasteners.
• 12-point: Easier to align in tight spaces because it engages in more positions, which can speed up work on lighter-duty tasks.

If you’re using an impact wrench, look for impact-rated sockets and consider thin-wall options if clearance is tight. Choose deep for longer bolts or nuts on studs, and shallow when space is limited. Reviewing these details on the product page can help you pick the right 17mm socket.
