Draper Metric Socket Set, 1/4" Sq. Dr. (27 Piece)

The Draper BD27M/PR Metric Socket Set builds on the essentials of a compact 1/4" drive kit by pairing twelve metric sockets with a comprehensive 14-piece screwdriver bit socket assortment — all on a single, tidy socket rack. The result is a versatile everyday set that handles both nut and bolt work and driven fastener applications without the need to reach for a separate tool.

The twelve sockets cover 4mm to 13mm in half-millimetre increments where it matters most — including the 4.5mm and 5.5mm sizes that many competing sets omit. This finer size graduation makes the BD27M/PR notably more useful across European automotive applications, consumer electronics, and precision assembly work where non-standard fastener sizes are commonly encountered.

The 14 screwdriver bit sockets span four of the most widely used fastener drive profiles. Three plain slot sizes (4mm, 5.5mm, 7mm) cover traditional slotted fasteners. Three cross slot sizes (No.1–3) handle standard Phillips-type screws across the full range of screw gauges. Five TX-STAR® sizes (T10, T15, T20, T25, T30) address the Torx fasteners found throughout modern automotive, appliance, and electronics manufacture. Three hex bit sockets (4mm, 5mm, 6mm) complete the set for cap head bolts and grub screws. Together, this selection makes the BD27M/PR a genuinely capable single-tool solution for a wide variety of workshop, automotive, and maintenance tasks.

All sockets and bit sockets are manufactured from chrome vanadium steel, hardened and tempered for durability, and satin chrome plated against corrosion. The 72-tooth reversible ratchet offers a 5° swing arc, quick-release socket changing, and a comfortable soft-grip handle for extended use.

The entire 27-piece set is supplied on a socket rack rather than in a bulky moulded case, keeping every piece clearly visible, easily grabbed, and straightforward to store in a tool chest drawer or carry in a bag. Manufactured and tested in accordance with DIN3122 and ISO3315 specifications, this set delivers reliable performance for professional tradespeople and skilled home users alike.

What's in the Box

Supplied on a socket rack for storage and transportation.

What makes this set different from a standard 12-piece socket set? In addition to twelve metric sockets, the BD27M/PR includes 14 screwdriver bit sockets covering plain slot, cross slot, TX-STAR®, and hex profiles. This means the same ratchet can drive both nuts and bolts and a wide range of threaded fasteners without switching to a separate screwdriver or bit driver — significantly broadening the kit's usefulness for a modest increase in size.

Why does this set include 4.5mm and 5.5mm sockets? Many budget socket sets jump from 4mm directly to 5mm, skipping the half-millimetre sizes. The BD27M/PR includes 4.5mm and 5.5mm sockets, which are commonly found on European-manufactured vehicles, consumer electronics, and precision mechanical assemblies. Their inclusion means this set covers the full practical range of small metric fasteners rather than leaving gaps that force improvisation.

What screwdriver bit profiles are included? The set covers four profiles: plain slot (4mm, 5.5mm, 7mm), cross slot (No.1, No.2, No.3), TX-STAR® (T10, T15, T20, T25, T30), and hex (4mm, 5mm, 6mm). These address the most commonly encountered fastener drive types in automotive, domestic appliance, electronics, and general construction applications.

How is the set stored? The BD27M/PR is supplied on a socket rack rather than in a moulded plastic case. This keeps all 27 pieces clearly visible and instantly accessible, and the rack is well suited to tool chest drawers, shelving, or carrying in a tool bag without unnecessary bulk.

What drive size is this set? This set uses a 1/4" square drive, designed for lower-torque, precision applications. It is the most appropriate drive size for the small fastener range covered — from 4mm sockets up to 13mm — providing the control and feel needed for fine mechanical work.

Is this set manufactured to a recognised standard? Yes. The BD27M/PR is manufactured from chrome vanadium steel, hardened, tempered, and satin chrome plated, and is tested in accordance with DIN3122 and ISO3315 specifications.
