Lock Wire Stainless 1 lb Dispenser .041 in (1.04 mm) MC0410-1#D

Description

Product Overview

WCS presents a premium stainless steel lock wire designed for the most demanding aerospace and industrial environments. The wire is drawn solid, polished to a mirror‑like finish, and supplied in a rugged 1 lb dispenser that feeds smoothly without kinking. With a diameter of .041 in (1.04 mm), it meets the exacting standards of NASM20995C, MS20995C, ASTM A580 Cond A, and AMS5697, ensuring compatibility with a wide range of fastener sizes and applications. The model MC0410-1#D is engineered for consistent tensile strength, corrosion resistance, and long‑term durability, making it an essential component for aircraft, helicopters, and heavy‑duty workshop projects.

Usage

Lock wire is the go‑to method for preventing critical fasteners from loosening due to vibration, thermal cycling, or mechanical shock. In aviation, it secures nuts on engine mounts, wing spars, and control surface linkages, where a single loose bolt can compromise safety. Ground‑based mechanics rely on the same principle to lock bolts on heavy equipment, agricultural machinery, and even automotive racing components. The dispenser’s dual‑cleat design and belt clip allow technicians to keep the wire within easy reach, whether they are working inside a cramped cockpit, a garage bay, or a field maintenance tent. The polished surface not only resists rust but also provides high visibility, reducing the chance of missed or improperly installed lock wire during inspections.

FAQ

What makes stainless steel lock wire preferable to other materials?

Stainless steel offers a unique combination of tensile strength, corrosion resistance, and temperature tolerance that other alloys cannot match. In aviation, exposure to moisture, salt, and extreme temperature swings is common; stainless steel lock wire maintains its integrity under these conditions, preventing fastener loosening and reducing maintenance intervals. The polished surface also reflects light, aiding visual inspections and ensuring that any missing or improperly installed wire is quickly identified.

How do I determine the correct wire diameter for my application?

The appropriate diameter depends on the size of the fastener and the level of vibration it will encounter. For most aircraft nuts and bolts, a .041 in (1.04 mm) lock wire provides a balance of strength and flexibility, meeting the NASM and AMS specifications. When working with larger bolts or higher‑stress locations, consider moving up to .051 in or .063 in diameters, which are also available in our product line. Always consult the aircraft maintenance manual or the equipment manufacturer’s guidelines to confirm the required size.

Can the lock wire be reused after removal?

While it is technically possible to reuse lock wire, industry best practices recommend installing fresh wire for each maintenance cycle. Reusing wire can introduce hidden fatigue, reduce tensile strength, and compromise the polished finish that aids visual inspection. New wire ensures that the locking torque is consistent and that the wire’s corrosion‑resistant coating remains intact, providing the highest level of safety and reliability.

What steps should I follow to install lock wire correctly?

Begin by cleaning the fastener and surrounding area to remove any debris or oil. Thread the lock wire through the designated holes, forming a figure‑eight pattern that locks the nut in place. Pull the wire taut, then twist the ends together using pliers, creating a secure knot. Trim any excess wire, and verify that the lock wire is visible and not obstructing moving parts. Finally, document the installation in the maintenance log, noting the wire size and installation date for future reference.

Is the dispenser compatible with other lock wire sizes?

Yes, the dispenser is designed with a universal feed mechanism that accommodates a range of wire diameters from .020 in to .063 in. The internal channel is tapered to prevent jamming, and the dual‑cleat system ensures smooth dispensing regardless of wire thickness. When switching sizes, simply unwind the remaining wire, clean the channel, and load the new wire spool. This flexibility makes the dispenser a versatile tool for workshops that service multiple aircraft models or industrial equipment.
