Socket set 1/2" spline 10–24 mm, 8 pieces — NEO tools 08-651

NEO tools 08-651 is an 8-piece spline socket set with a 1/2" drive, covering metric sizes from 10 mm to 24 mm. The set contains spline-profile sockets intended for fastening and loosening spline-headed fasteners commonly used in automotive, industrial and mechanical assemblies. Designed to provide a compact selection of frequently used sizes, this kit supports repair, maintenance and assembly tasks where spline fittings are specified.

Advantages

The spline profile ensures even distribution of torque across the fastener head, reducing the risk of rounding and damage compared with standard hex sockets. A 1/2" drive offers sufficient torque capacity for heavy-duty applications while maintaining compatibility with common ratchets and extension bars. The set’s size range from 10 mm to 24 mm covers typical metric spline fasteners used in engines, gearboxes and industrial equipment. Components are organized to make selection and transport convenient in workshops and service vehicles.

Suitable for

• Automotive repair and maintenance
• Industrial machinery assembly and servicing
• Mechanical workshops and professional technicians
• DIY projects requiring spline fastener access

Key specifications

• Drive type: 1/2" square drive
• Spline socket sizes: 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 17 mm, 19 mm, 24 mm
• Number of pieces: 8
• Socket profile: spline
• Intended application: fastening and loosening spline-headed fasteners

How to use

Select the socket that matches the spline fastener size and attach it securely to a 1/2" ratchet or breaker bar. Seat the socket fully on the fastener head before applying torque to ensure an even load on the spline profile. For loosening seized or corroded fasteners, apply steady, controlled force and consider using penetrating lubricant or gradual impact techniques as appropriate. After use, clean debris from the sockets and store them in their case to maintain fit and prevent corrosion.

Usage recommendations

Use the correct socket size for spline fasteners to avoid damaging the fastener profile. For high-torque applications, use longer handles or torque-limiting tools rated for the required torque and inspect sockets regularly for wear or deformation.
