V420258 Screw

V420258 Screw – The Ultimate Oil Sump Sealing Plug

The V420258 Screw is a precision‑engineered oil sump sealing plug designed to provide reliable, leak‑free performance in a wide range of automotive engines. Its robust construction and exacting tolerances make it an essential component for maintaining engine integrity and ensuring optimal lubrication.

Key Features & Technical Specifications

• Thread Size: M10 x 1.25 mm – a standard metric thread that fits most modern oil sump designs.
• Length: 13 mm – engineered to match the typical depth of oil sump cavities, ensuring full engagement with the mating surface.
• Material Composition: High‑strength alloy steel treated with a corrosion‑resistant coating for durability under high pressure and temperature conditions.
• Sealing Mechanism: Integrated rubber or elastomeric gasket (depending on variant) that provides an airtight seal against oil leakage.
• Application Range: Compatible with a broad spectrum of vehicle makes and models, including but not limited to Citroën, Ford, Fiat, Peugeot, Mazda, Toyota, and Volvo.

Design Excellence for Optimal Performance

The V420258 Screw incorporates a double‑threaded head that allows for precise torque application during installation. This design minimizes the risk of cross‑threading or stripping, which can compromise the seal and lead to oil loss.

Its tapered internal geometry ensures a snug fit against the sump’s mating surface, creating a uniform pressure distribution across the sealing gasket. The result is a long‑lasting seal that resists vibration, thermal expansion, and mechanical stress.

Installation Guide

1. Preparation: Clean the oil sump opening thoroughly to remove any debris or old gasket material.
2. Gasket Placement: Slide a new rubber gasket onto the screw’s threaded portion, ensuring it sits flush against the sump surface.
3. Screw Insertion: Hand‑tighten the V420258 Screw into the oil sump opening until it is fully seated.
4. Tightening: Use a calibrated torque wrench to apply the manufacturer’s recommended torque value (typically between 15–20 Nm for M10 screws). This ensures optimal sealing without over‑tightening.
5. Verification: Inspect the installation visually and, if possible, perform a pressure test to confirm that no oil leaks are present.

Why Choose the V420258 Screw?

• Reliability: Proven track record in high‑performance engines where oil integrity is critical.
• Versatility: Designed to fit a wide array of vehicle models, reducing the need for multiple spare parts inventories.
• Durability: High‑grade materials and protective coatings resist corrosion, oxidation, and wear over extended service periods.
• Ease of Replacement: Standard M10 thread size allows mechanics to use common tools, speeding up maintenance tasks.

Compatibility Overview
