MS35214-42 - Pan Head Machine Screw 1/2 8-32

MS35214-42 – Pan Head Machine Screw 1/2 8-32

Available now on the Airparts.aero Marketplace.

Overview

The MS35214-42 is a military-standard pan head machine screw engineered for specific non-structural applications within aircraft, particularly in instrument mounting and cockpit assemblies. Conforming to the rigorous MS35214 standard, this fastener is differentiated by its material composition—a high-quality copper alloy (brass)—which provides excellent natural corrosion resistance and non-magnetic properties. The pan head design offers a low-profile, clean finish with a broad bearing surface, making it an ideal and certified choice for securing instruments and panels where a non-steel fastener is required.

Key Features

• Copper Alloy (Brass) Construction: Fabricated from a high-quality brass alloy. This material is inherently resistant to corrosion and is non-magnetic, which is critical for fasteners used in close proximity to sensitive magnetic compasses and other flight instruments.
• Pan Head Design: Features a versatile pan head with a flat bearing surface that provides good clamping force without a high profile. This ensures a secure fit for panels and components without creating an obstruction.
• Black Oxide Finish: Coated with a durable, black chemical oxide finish. This non-reflective coating is ideal for use within the cockpit and on instrument panels to minimize glare and reflections, enhancing pilot readability.
• MS Certified Quality: As a certified Military Standard part, the MS35214-42 guarantees full traceability, dimensional accuracy, and material composition, ensuring it meets the highest quality standards for aviation use.
• Non-Structural Application: Specifically designed for light-duty applications where the high tensile strength of steel is not required, but material properties like corrosion resistance and non-interference are paramount.

Aircraft Compatibility

The MS35214-42 is a standard component used across a vast range of general aviation, commercial, and military aircraft. Its use is specified by manufacturers wherever a non-magnetic, corrosion-resistant machine screw of this size is needed.

• Common Applications:
  • Instrument Panel Installation: Securing flight instruments, gauges, and avionics faceplates.
  • Interior Components: Fastening trim pieces, placards, and cabin furnishings.
  • Electrical Grounding: Used in specific applications where a brass screw is required for electrical conductivity or to prevent galvanic corrosion with other materials.
  • Light-Duty Panel Fastening: Attaching inspection covers and panels where structural loads are not a factor.

Applications

The MS35214-42 is the specified fastener for applications where its unique material properties are essential:

• Non-Magnetic Zones: Crucial for installations near magnetic compasses or other instruments sensitive to magnetic interference.
• Corrosion-Prone Areas: Provides a durable fastening solution in areas where moisture may be present.
• Instrument Assembly: The black, non-reflective head is standard for visible fasteners on instrument panels to reduce glare for the pilot.

Why Choose MS35214-42?

Using the correct, certified hardware is a cornerstone of aviation safety and airworthiness. The MS35214-42 screw provides the specific non-magnetic and corrosion-resistant properties required for many cockpit and instrument installations. Substituting with a standard steel screw could induce compass errors or lead to premature corrosion. By choosing a genuine MS35214-42, you are ensuring the use of a fastener with a certified material pedigree, correct dimensions, and a finish designed for the specific challenges of the flight deck environment.

The Military Standard MS35214 specification is dedicated to a series of pan head, cross-recessed machine screws made from copper alloy (brass). This standard fills a critical niche where the properties of steel are undesirable. Brass offers excellent resistance to corrosion, especially in moist environments, and is inherently non-magnetic, making it the ideal choice for fasteners near sensitive avionics. The black oxide finish is not for corrosion protection (as the brass itself is resistant) but is primarily a surface treatment to reduce reflectivity, a key human factors consideration in cockpit design. The coarse UNC thread pattern ensures quick and easy assembly without the risk of cross-threading, which is ideal for maintenance and installation tasks.

Note: Always verify the correct screw part number (including material, thread size, and length) from the applicable aircraft maintenance manual or Illustrated Parts Catalog (IPC). The use of a brass screw is often a specific engineering choice that should not be substituted.
