BMW Genuine Oval-Head Screw + Spring Washer 07145A48F73

Secure structural brackets exactly as the factory intended with this M8 × 25 mm oval-head screw (parts label 07 14 5 A48 F73 / 07145A48F73). Used throughout BMW G-series chassis, the fastener pairs a low-profile oval (pan) Torx head with a pre-installed spring washer, delivering vibration-proof clamping and consistent torque every time the bolt is serviced.

Key Benefits

• Factory Dimensions – metric M8 thread, 1.25 mm pitch, 25 mm shank length; direct replacement for any bolt etched 07145A48F73.

• High-Strength Steel – property class 10.9 (1 000 MPa tensile) handles dynamic suspension loads without stretching.

• Zinc-Nickel (ZNS3) Coating – triple-layer passivation shields the threads against road salt, humidity and engine-bay chemicals.

• Captive Spring Washer – serrated edge locks against loosening, maintaining preload on subframe and crash-beam joints.

• Torx T40 Oval Head – broad, low-profile head clears adjacent components; Torx drive prevents tool slip for precise torque.

Typical Applications*

Technical Specification

1. Clean female threads; chase with an M8 × 1.25 tap if corroded.

2. Apply medium-strength thread-locker when specified in the workshop manual.

3. Torque to the exact value listed for your assembly—over-tightening risks thread distortion.

4. Mark the head with a paint dot for future inspection of movement or loosening.
