29-Piece vs 39-Piece Impact Socket Set: SAE + Metric Deep or Metric Deep + Shallow?
VEVOR Guide
29-Piece vs 39-Piece Impact Socket Set: SAE + Metric Deep or Metric Deep + Shallow?
Both VEVOR sets use a 1/2 in drive, six-point profile, Cr-V alloy steel, and a carrying case. The real choice is not just piece count: one set combines SAE and metric deep sockets with extension bars, while the other focuses on metric sizes in both deep and shallow formats.
Quick answer
Choose the 29-piece set if you regularly work with both SAE and metric fasteners and mainly need deep sockets. Choose the 39-piece set if your work is metric-only and you want both deep and shallow access across a wider metric range.
Side-by-side comparison
| Feature | 29-Piece Set | 39-Piece Set |
|---|---|---|
| Drive size | 1/2 in | 1/2 in |
| Socket profile | 6-point | 6-point |
| Depth | Deep only | Deep + shallow |
| SAE | 11 deep sockets, 3/8–1 in | Not included |
| Metric | 15 deep sockets, 10–24 mm | 19 deep + 19 shallow, 9–24, 26, 27, 30 mm |
| Accessories | 3, 5, 10 in extension bars | Universal joint |
| Material | Heat-treated Cr-V | Heat-treated Cr-V |
Why choose the 29-piece SAE + Metric set?
- You work on a mix of domestic, imported, older, or general equipment using both measurement systems.
- You mainly need deep sockets for recessed nuts or exposed studs.
- You value 3, 5, and 10 inch extension bars for extra reach.
- You do not need shallow socket duplicates.
Why choose the 39-piece Metric set?
- Your vehicles or equipment are primarily metric.
- You want the same common metric sizes in both deep and shallow formats.
- You need larger metric sizes up to 30 mm on the listed set.
- You value a universal joint for angled access.
Deep vs shallow impact sockets
Deep sockets help reach nuts on longer studs and recessed fasteners. Shallow sockets take up less space and can fit where clearance is tight. If your work routinely includes both situations, the 39-piece metric set gives you both depths. If you mainly need longer reach and mixed SAE/metric coverage, the 29-piece set is the more logical fit.
Check the exact included sizes
The 29-piece set includes metric sizes from 10–24 mm and SAE sizes from 3/8–1 in. The 39-piece set includes metric sizes 9–24 mm plus 26, 27, and 30 mm in both deep and shallow versions. It does not include 25, 28, or 29 mm.
Impact socket material and fit
Both sets use heat-treated Cr-V alloy steel with black phosphate finish and laser/stamped size markings. Both are six-point 1/2 in drive socket sets. Match the socket size precisely to the fastener and use the set with compatible impact-rated tools and accessories.

FAQ
Which set is better for automotive work?
If your vehicles use both SAE and metric fasteners, the 29-piece set is more versatile. If your work is metric-only and you need both deep and shallow access, the 39-piece set is the better fit.
Does the 39-piece set include SAE sockets?
No. It is a metric-only set.
Does the 29-piece set include shallow sockets?
No. Its sockets are all deep sockets, plus three extension bars.
