Description
Overview:
This Self-tapping Screw DIN 7500 - 10-32 x 3/8" (approx. 9.5 mm length) is a genuine Stihl OEM fastener designed for reliable use in Viking and Stihl lawn mowers, including MB 450 and MB 455. It is a steel, thread-forming screw that creates its own mating thread in suitable materials for a secure, vibration-resistant hold. The 10-32 thread has an approximate major diameter of 0.190" (about 4.83 mm) with 32 TPI (thread pitch approx. 0.79 mm), providing a fine, tight fit where precision is required. Built to DIN 7500 standards, it is suited to fixing covers, guards, housings, and brackets where repeatable, consistent assembly is important. A practical replacement choice for routine maintenance and repair on compatible Viking/Stihl machines.
Key Features:
- Genuine Stihl part for assured fit and performance on listed Viking/Stihl models
- Self-threading (thread-forming) action for strong, repeatable fastening in prepared holes
- Fine 10-32 thread for precise clamping and reduced loosening under vibration
- Length 3/8" (approx. 9.5 mm) for compact assemblies and shallow cavities
- Made from durable steel for strength and long service life
- Complies with DIN 7500 for consistency and reliability
- Clean installation with minimal risk of cross-threading when fitted correctly
- Suitable for routine maintenance tasks and part replacements in mower assemblies
Typical Applications:
Used to secure mower decks, engine shrouds, handle brackets, cable clips, covers, and plastic/metal housings on Viking and Stihl pedestrian mowers. Ideal where a compact fastener is needed to bite and hold in existing pilot holes, helping prevent loosening from vibration during regular mowing. Common in routine servicing, part replacement, and repairs after impact or wear.
