Blue Spot Tools Individual 21mm Shallow Hex Socket (1/2" Drive)

MPN: 01733

Barcode: 5028734017335

Size: 21mm

Weight: 0.08kg

Overview:

The Blue Spot Tools 21mm Shallow Hex Socket is a 1/2" drive CrV steel socket designed for high-torque hand tool work. It connects to any standard 1/2" drive ratchet, breaker bar, or torque wrench and handles the sustained load applied through each.

The body carries a mirror-polished finish that resists surface build-up and keeps the socket looking presentable in a working environment. A knurled band at the mid-point of the socket adds a grip reference when placing or pulling the socket in tight or oily conditions.

The 38mm shallow depth makes this socket practical for fasteners in spots where a deeper socket won't fit or won't sit square. No adapter is required for any standard 1/2" drive tool.

Key Features and Benefits

• CrV Steel: Handles the sustained torque applied through 1/2" drive ratchets and breaker bars
• High-Torque Capability: Rated to 569Nm for demanding automotive and workshop fasteners
• Six-Point Hex: Contacts the flat sides of fastener heads throughout the arc of rotation
• Mirror Polished: Resists surface build-up and cleans down quickly in working conditions
• Knurled Mid-Band: Adds a grip reference point when placing or retrieving the socket
• Fits All 1/2" Drive Tools: Connects to ratchets, torque wrenches, and breaker bars
• 38mm Depth: Fits in spaces where a deeper socket won't seat or clear surrounding components

Specs & Attributes

• Size: 21mm

Typical Applications

• Wheel nut removal and refitting on cars and light commercial vehicles
• Anti-roll bar link and drop link fasteners
• Rear axle and hub carrier bolts
• Exhaust clamp and hanger hardware
• General 1/2" drive hand tools work on 21mm metric fasteners

How to Use

• Confirm the Fastener Size: Check that the head measures 21mm across the flat faces before fitting the socket.

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

• Seat the Socket: Place the hex opening over the fastener head - it should sit flat with no rocking before any force is applied.

• Apply the Required Torque: Drive the fastener in the correct direction, staying within the 569Nm limit.

• Remove After Use: Disengage the drive tool and use the knurled band to grip and withdraw the socket.

Frequently Asked Questions (FAQs)

• What fasteners commonly need a 21mm socket?
  A 21mm socket is frequently used for wheel nuts across a range of cars and light commercial vehicles, as well as anti-roll bar links, hub carrier bolts, and various chassis fasteners. It is a well-used size in general vehicle maintenance.

• What is the difference between buying a socket set and individual sockets?
  A socket set covers a range of sizes in one purchase - practical for general workshop use. Individual sockets fill gaps in an existing set or replace a single worn or missing size without requiring a full purchase again. They are also the right choice when only one specific size is needed for a single job.

• How does a ratchet work when used with a socket?
  A ratchet uses an internal pawl that locks in one rotational direction and frees in the other. This lets the handle swing back and reset without lifting the socket off the fastener, allowing continuous tightening or loosening without interruption.

• At what angle should a socket be seated on a fastener?
  The socket must sit square, perpendicular to the fastener axis. Seating it at an angle reduces contact between the hex profile and the fastener faces, concentrating load on fewer points. Under torque, this increases the risk of rounding the fastener head.

• Are chrome vanadium sockets suitable for professional workshop use?
  Chrome vanadium sockets are suited to hand-driven applications, including ratchets, torque wrenches, and breaker bars, and are widely used in professional workshops for manual torque work. For impact wrench use, chrome molybdenum impact-rated sockets are the appropriate choice, as they are designed to absorb the shock loads generated by power tools.

Summary

The Blue Spot Tools 21mm Shallow Hex Socket is a CrV 1/2" drive hand tool socket rated to 569Nm for automotive and workshop applications. The 38mm depth makes it usable in tight access points where deeper sockets lack the clearance to seat correctly. This socket is backed by the Blue Spot Tools Lifetime Guarantee.
