Blue Spot Tools Individual 18mm Shallow Hex Socket (1/2" Drive)

MPN: 01730

Barcode: 5028734017304

Size: 18mm

Weight: 0.09kg

Overview:

The Blue Spot Tools 18mm Shallow Hex Socket takes a 1/2" drive and is built from chrome vanadium steel for hand-driven high-torque work. The six-point hex opening makes full contact with the flat faces of a fastener head when correctly seated.

The mirror-polished chrome surface cleans easily after a workshop session. A knurled band runs around the mid-section of the socket body, providing a grip surface when handling with oily or gloved hands.

At 38mm deep, the socket seats correctly on bolt heads in confined locations where longer sockets would not clear. It connects directly to any standard 1/2" drive ratchet, breaker bar, or torque wrench.

Key Features and Benefits

• Chrome Vanadium Construction: Handles hand-driven high-torque work through 1/2" drive tools
• 477Nm Torque Rating: Rated for the demands of automotive and workshop fasteners at this size
• Six-Point Hex Profile: Full face-to-face contact with the fastener reduces corner loading under torque
• Mirror Polished Chrome: Cleans off quickly and resists surface corrosion in workshop conditions
• Knurled Mid-Section: Grip surface when handling with oily hands or workshop gloves
• 1/2" Drive Fitting: Connects directly to ratchets, torque wrenches, and breaker bars
• 38mm Depth: Seats correctly in tight spaces where a deeper socket would not clear

Specs & Attributes

• Size: 18mm
• Drive: 1/2"
• Type: Hex (6-point)
• Material: Chrome Vanadium (CrV)
• Finish: Mirror polished with knurled grip band
• Max Torque: 477Nm

Typical Applications

• Cylinder head bolts where the torque requirements fall within the socket's rated limit
• Alternator and ancillary bracket mounting fasteners
• Lower suspension arm and axle beam fasteners
• Exhaust manifold and system hardware
• General 1/2" drive hand tool works on 18mm metric fasteners

How to Use

• Check the Fastener Size: Confirm the bolt head or nut measures 18mm across the flat faces before fitting.

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

• Seat the Socket: Place the hex opening squarely over the fastener - no rocking should be present before torque is applied.

• Drive the Fastener: Apply force in the required direction without exceeding 477Nm.

• Remove After Use: Disengage the drive tool and use the knurled section to pull the socket clear.

Frequently Asked Questions (FAQs)

• What is an 18mm socket used for?
  An 18mm socket handles cylinder head bolts on some engine designs, alternator and ancillary bracket fasteners, lower suspension hardware, and exhaust system components. It is a common metric size across a range of European and Asian vehicles.

• What is the structural difference between a standard socket and an impact socket?
  A standard chrome vanadium socket has thinner walls and a harder steel composition suited to manual torque application. An impact socket uses a different alloy with thicker walls and a softer temper, designed to absorb the repeated shock loads produced by impact wrenches. Mixing the two categories at full power tool output is not a safe practice.

• How do I approach a seized or corroded fastener with a socket?
  A six-point hex socket seated square on the flats gives the strongest grip on a corroded fastener head. Apply penetrating fluid in advance to free the thread corrosion. Use a breaker bar for steady leverage rather than sharp force. If the fastener still won't move, additional heat or specialist extraction tooling may be required.

• Do chrome vanadium sockets corrode over time?
  Chrome vanadium sockets with a mirror-polished finish resist everyday surface corrosion in normal workshop conditions. Prolonged exposure to moisture, salt spray, or corrosive chemicals will affect any steel tool over time. Keeping sockets dry and stored correctly between uses reduces this risk significantly.

• What is vanadium, and why is it added to tool steel?
  Vanadium is a metal added in small quantities to steel alloys to increase hardness and resistance to wear and deformation. In combination with chromium, which improves corrosion resistance, the resulting chrome vanadium alloy gives hand tool sockets the toughness needed to handle repeated high-torque loading without cracking or distorting.

Summary

The Blue Spot Tools 18mm Shallow Hex Socket is a CrV 1/2" drive hand tool socket rated to 477Nm. The 38mm depth suits fastener heads in tight working spaces where a deeper socket would not seat properly. This socket is backed by the Blue Spot Tools Lifetime Guarantee.
