IMSCREWS M3 Spring Lock Washers 200 Pcs, 304 Stainless Steel GB93 Metric Split Washers, OD 5.0mm ID 3.2mm, Burr-Free Fasteners for Electronics Assembly

Product Technical Specifications Brand: IMSCREWS Size: M3 (Metric) Standard: GB93 Material: 304 Stainless Steel Inner Diameter (ID): 3.2mm Outer Diameter (OD): 5.0mm Craftsmanship: Flat Cut, Burr-Free Package Quantity: 200 Pieces Packaging Type: IMSCREWS Custom Zip-lock Bag Common Applications & Installation Designed specifically for precision micro-assembly, these M3 spring lock washers are highly effective for PC motherboard installations, 3D printer builds, drone maintenance, and RC model modifications. They provide crucial tension to resist loosening caused by operational vibrations. Frequently Asked Questions (FAQ) Are these washers corrosion resistant? Yes. They are manufactured from high-grade 304 stainless steel, which provides reliable resistance against rust and corrosion, making them highly dependable for long-term use in typical indoor and clean environments. Can they be used outdoors? While 304 stainless steel offers good corrosion resistance, these micro-sized M3 washers are primarily recommended for indoor precision instruments and electronic devices. For prolonged exposure to harsh outdoor elements, specialized outdoor coatings might be required. Do they work with bolts? Yes. These GB93 split washers are engineered to work efficiently with standard M3 metric bolts and nuts. When compressed between the bolt head and the mounting surface, they provide the necessary spring tension to prevent the fastener from backing out. Are they reusable? Spring lock washers function by applying continuous tension. Repeated tightening and loosening can cause the material to experience elastic fatigue, reducing its effectiveness. For precision applications or high-vibration environments, single-use is generally recommended for optimal security.

• 【GB93 METRIC M3 SPECIFICATIONS】 Strictly manufactured to GB93 metric standards, these M3 spring lock washers feature a 3.2mm inner diameter and a 5.0mm outer diameter. The precise dimensions ensure consistent tension and secure fastening for micro mechanical joints.
• 【PREMIUM 304 STAINLESS STEEL】 Crafted from high-grade 304 stainless steel, offering reliable corrosion resistance for indoor precision instruments and electronic devices. The flat cut and burr-free edges prevent scratching or damaging sensitive components during installation.
• 【PHYSICAL PROPERTIES NOTICE】 Due to the standard cold-working manufacturing process of 304 stainless steel, these spring washers will naturally exhibit weak magnetic properties. This is a common physical characteristic and does not indicate a compromise in material quality.
• 【SECURE BRANDED PACKAGING】 To prevent the loss of micro-fasteners during transit, all 200 pieces are securely packed in a custom IMSCREWS brand zip-lock bag. This durable design ensures neat storage and easy access for intricate electronic repairs or 3D printer assembly.
• 【VERSATILE INDOOR APPLICATIONS】 Engineered to work efficiently with M3 metric bolts and nuts. These split washers provide effective anti-loosening vibration resistance, making them highly suitable for PC motherboards, RC models, drones, and household appliance maintenance.
