Bahco Reversible Ratchet Ring Spanner Set — 4 Piece, 8–27mm
Part No: S4RM/4T | Barcode: 7314150179916
The Bahco S4RM/4T is a 4-piece reversible ratchet ring spanner set that packs 16 metric sizes from 8 to 27mm into four tools — fast nut-and-bolt work for automotive and machinery maintenance. Each spanner carries two ratcheting ring sizes with a 12-point Dynamic-Drive profile, and a 5° operating angle lets it work in tight quarters where a standard spanner cannot swing.

Key Features & Benefits
- 4-in-1 reversible heads — four double-ended spanners cover 16 sizes — far less to carry than a full single-size set.
- Dynamic-Drive™ 12-point profile — grips on the flats rather than the corners, giving longer life to both spanner and fastener.
- 5° operating angle — needs only a small swing to advance the ratchet — ideal for confined engine bays and frames.
- Flip-lever reversing — change between tighten and loosen with a thumb flick without removing the head.
When to Use This Set
Reach for the S4RM/4T when you need wide ratcheting coverage in one compact set — it extends past the 3-piece S4RM/3T to include the larger 21–27mm sizes for suspension, driveline and heavier fasteners. Best where access is tight and speed matters.
Pro Tip: The 5° ratchet angle shines on bolts you can barely reach — even a tiny back-and-forth wrist movement advances the nut, so you can run fasteners in spots too tight for a conventional ring spanner.
