H&R 15255707 SET - M15x1.25 57 mm Floating-Ball Wheel Bolt Kit (10-Bolts Pack)

Product Overview

The H&R 15255707 SET is a premium wheel-bolt kit engineered for secure, reliable wheel mounting - ideal as replacement bolts or when mounting wheels/spacers that require extended-length hardware. Each bolt uses thread size M15x1.25 with a 57 mm shaft length and a floating ball-seat (round head) design, ensuring proper seating and secure clamping. The set includes 10 bolts, covering one 5-lug axle.

Features

• Thread size: M15 x 1.25 - metric bolt threading standard for many European 5-lug hubs
• Shaft length: 57 mm - extra length to accommodate spacers, deep-offset wheels, or increased hub-to-wheel distance
• Seat type: Floating ball / round head seat - designed for correct seating in wheels that require ball-seat bolts
• Head/socket size: 19 mm hex - compatible with common wheel-bolt tools and torque wrenches
• Finish: corrosion-resistant coating (silver or black depending on variant) - for long-term durability in daily driving conditions
• Pack quantity: 10 bolts - enough for a full 5-lug axle or replacement of all bolts
• Manufactured to H&R's quality standards for wheel fastening safety and reliability

Usage & Fitment Guidance

The 15255707 SET is intended for vehicles whose wheel-hub and wheels require M15x1.25 threaded bolts with a ball-seat design - particularly common among many European 5-lug makes (e.g. premium sedans/SUVs using M15 bolts). These bolts are especially useful when installing aftermarket wheels or wheel spacers that increase the hub-to-wheel distance, as the longer 57 mm shaft ensures proper thread engagement and safe clamping.

Important: Before ordering or installation, verify your wheel hub's bolt pattern, bolt seat type, hub-to-wheel offset, and required bolt length. Using incorrect bolts - or bolts too short - may lead to unsafe wheel mounting or failure under load.

Installation & Safety Notes

• Use a calibrated torque wrench and tighten bolts to the wheel/hub manufacturer's specified torque value.
• Ensure bolts thread in smoothly without cross-threading; verify wheel seats flush before final torqueing.
• If using spacers or deep-offset wheels, make sure 57 mm length provides sufficient thread engagement beyond spacer + wheel thickness.
• After installation, re-check bolt torque after first 50-100 km of driving; inspect periodically for tightness and corrosion - especially in harsh road conditions or when wheels are removed often.
