Key Features

Better Fastener Grip

DirectTorque technology is built to contact the fastener more effectively, which helps reduce rounding and gives you a more secure bite when you are working on small metric hardware.

Deep Socket Reach

This deep 5 mm socket gives extra clearance for nuts on longer studs and recessed fasteners, so you can reach hardware that a shallow socket may not fully cover.

1/4 Inch Drive Control

The DEWALT 5 mm 1/4 Inch Drive 6-Point Metric Deep Impact Socket is sized for lighter-duty fastening work where compact ratchets and small drive tools make more sense than bulkier setups.

Overview

The DEWALT 5 mm 1/4 Inch Drive 6-Point Metric Deep Impact Socket, model DWMT86102OSP, is a single metric deep socket built for turning 5 mm fasteners with a 1/4 inch drive ratchet or related drive tool. This is a deep socket designed for fastening and loosening small metric nuts and bolts. It is a good fit for mechanics, equipment maintenance, and serious DIY users who want the correct size instead of forcing a close-enough socket onto small hardware.

The key working feature here is the 6-point opening paired with DEWALT DirectTorque technology. In practical terms, that matters because small fasteners are easy to round off when the socket fit is sloppy or the contact point is wrong. A 6-point socket gives better engagement on the flats of the fastener than a 12-point pattern, which helps when you need solid grip on stubborn or already-worn hardware.

The deep well design gives this socket more reach than a standard shallow socket. That matters when a nut sits down on a stud, when hardware is recessed, or when surrounding parts limit how straight you can approach the fastener. On small metric service work, that extra depth can be the difference between getting the job done cleanly and having to stop and switch tools.

DEWALT lists chrome vanadium steel construction, which is a common choice for strength and durability in mechanics hand tools. The polished finish helps resist chipping and flaking, and it also makes cleanup easier when the socket picks up grease, dust, or general shop grime. Hard-stamped size markings are another detail that pays off over time because the size stays readable longer than lightly printed markings.

The knurled control ring is worth calling out on a socket this size. Small sockets are the ones you usually handle with oily fingers while working in tight spaces. A textured ring makes it easier to start the socket by hand, pull it from a rail or drawer, and keep control when you are swapping between sizes during repetitive fastening work.

Because this is a 1/4 inch drive metric socket, it fits naturally into compact ratchet and extension setups used for lower-torque service work. That makes it especially useful for automotive trim and interior fasteners, small engine service, bike and equipment repair, and general assembly tasks where oversized drive tools are unnecessary. If you regularly deal with 5 mm metric hardware and need the extra reach of a deep socket, this is the right kind of piece to keep in the drawer instead of improvising with the wrong size.

Reach Recessed 5 mm Fasteners

When a fastener sits below the surface or runs down a stud, a shallow socket can come up short. The deep profile on this socket gives the clearance needed to seat fully and turn small metric hardware without slipping off the corners.

• 5 mm metric size for small nuts and bolts
• Deep well design for longer studs and recessed access
• 1/4 inch drive format for compact ratchets and extensions

Tool Nut’s Take

Small Socket, Real Shop Value

The DEWALT 5 mm 1/4 Inch Drive 6-Point Metric Deep Impact Socket is the kind of single-size piece that earns its spot when you keep running into the same small metric fastener and want the right fit every time.

• Who it’s for: Mechanics, maintenance techs, and DIY users who work on small metric hardware and want a proper deep socket instead of making a shallow one do a job it was not built for.
• Why it stands out: The 6-point design, DirectTorque feature, and deep reach all work together to improve grip on small fasteners where rounding is easy and access is often tight.
• Worth knowing: This is a single open-stock socket, not a set, so it makes the most sense when you specifically need a 5 mm deep socket in a 1/4 inch drive.

Common Questions

• Is this a metric or SAE socket? It is a metric socket, sized at 5 mm.
• Is this a deep or shallow socket? This is a deep socket.
• What drive size does it use? It uses a 1/4 inch drive.
• How many points does the socket have? It has a 6-point configuration for stronger fastener contact.
