Blue Spot Tools Individual 27mm Shallow Hex Socket (1/2" Drive)

MPN: 01737

Barcode: 5028734017373

Size: 27mm

Weight: 0.15kg

Overview:

The Blue Spot Tools 27mm Shallow Hex Socket is a chrome vanadium, 1/2" drive socket for high-torque hand tool applications. The six-point hex opening contacts the flat faces of the fastener head, giving solid engagement through the full range of the turn.

The mirror-polished body stays presentable and cleans down quickly. A knurled band at the mid-section provides grip during placement and retrieval, even when hands or gloves carry oil or grease. With a 38mm depth, the socket sits well within the range needed for bolt heads in tighter access points. It pairs with all standard 1/2" drive hand tools without the need for an adapter.

Key Features and Benefits

• Chrome Vanadium Steel: Provides the hardness and toughness required for sustained high-torque hand tool work
• High-Torque Rated: Handles large automotive and workshop fasteners up to the 569Nm limit
• Six-Point Hex Opening: Full contact with the flat faces of the fastener reduces the chance of rounding under load
• Mirror Polished Finish: Cleans down quickly and resists surface build-up between jobs
• Knurled Mid-Section: Retains control of the socket during placement or removal in greasy conditions
• Fits All 1/2" Drive Tools: Connects to ratchets, torque wrenches, and breaker bars without an adapter
• Shallow Profile: Works in access points where overhead clearance rules out a longer socket

How to Use

• Confirm the Fastener Size: Check the measurement across the flats reads 27mm before starting.

• Attach to a 1/2" Drive Tool: Fit the socket onto a ratchet, breaker bar, or torque wrench.

• Seat the Socket: Place the hex opening over the fastener head and check that there is no rocking or play before applying force.

• Apply Rotational Force: Drive the fastener in the required direction. Stay within the 569Nm maximum torque rating.

• Remove After Use: Disengage the drive tool, then grip the knurled band to pull the socket clear by hand.

Frequently Asked Questions (FAQs)

• What is a 27mm socket commonly used for?
  A 27mm socket is regularly used on larger automotive fasteners such as brake calliper carriers, subframe bolts, and steering components. It sits at a size where 1/2" drive hand tools are the standard choice for applying sufficient torque safely.

• What does "hex" mean on a socket?
  Hex refers to the six-sided internal profile of the socket opening. It is shaped to match the six flat faces of a standard bolt head or nut. This design spreads the applied force across the full face of each side rather than concentrating it at the corners.

• Why is chrome vanadium steel used in hand tool sockets?
  Chrome vanadium offers a practical balance of hardness and toughness that suits hand-driven applications well. It resists the sustained torque loads applied through ratchets and breaker bars without the brittleness that would cause it to crack under normal working conditions.

• Can a socket be used without a ratchet?
  Yes. Sockets attach to any 1/2" drive tool, including breaker bars, torque wrenches, and sliding T-bars. For stubborn or heavily torqued fasteners, a breaker bar is often the better choice for initial loosening as it applies direct leverage without putting stress through a ratchet mechanism.

• How do I find the right socket size for a fastener?
  Measure across the flat faces of the bolt head or nut with a calliper. Alternatively, test-fit sockets until one drops on fully without play. The correct socket seats flat against all six faces of the fastener and does not rock when placed on it.

Summary

The Blue Spot Tools 27mm Shallow Hex Socket pairs CrV construction with a 1/2" drive and a 569Nm torque rating for demanding automotive and workshop fasteners. The 38mm shallow depth keeps the socket usable in areas where access above the bolt head is restricted. This socket is backed by the Blue Spot Tools Lifetime Guarantee.
