Chave de caixa HAZET 903SPC/3

Impact socket HAZET 903SPC/3 is a set of three long wheel sockets designed for mounting and dismounting alloy rims. The set includes three color-coded replaceable plastic sleeves (blue, red, yellow) to protect the rim surface and help quickly identify the correct size. Each socket features a plastic insert to protect the wheel bolt surface, a borehole for a locking pin or safety spring, and a groove for an O-ring. The tools are made in Germany and intended for use with a 12.5 mm (1/2 inch) square drive.

Advantages

The long design provides better access to deeply recessed wheel bolts. Color-coded outer sleeves speed up size selection while the replaceable plastic sleeves and internal plastic inserts reduce the risk of damaging alloy rims and wheel bolts. The hollow 12.5 mm square drive and outside hexagon traction profile ensure compatibility with common impact wrenches and hand tools.

• Mounting and dismounting alloy wheels on passenger vehicles
• Professional automotive workshops and tire service

How to use

Select the socket with the correct color-coded sleeve for the wheel bolt size, fit it onto the square 12.5 mm (1/2 inch) drive of an impact wrench or torque wrench, and engage the outside hexagon onto the bolt head. When working with alloy rims, ensure the plastic inserts and outer sleeves are correctly positioned to avoid metal-to-metal contact. Use the borehole if a locking pin or safety spring is required, and check the O-ring groove and sleeve condition before use.

Recommendations

Inspect the replaceable plastic sleeves and internal inserts regularly and replace them if worn to maintain rim protection. Use appropriate torque settings on impact or torque wrenches to prevent over-tightening of wheel bolts.
