Washer Head Machine Screw

Dazhe Washer Head Machine Screw – the all-in-one fastening solution that combines a screw and washer into a single, precision-engineered component. Designed for light to medium‑duty assembly, this screw delivers superior pressure distribution, protects delicate surfaces from dents and damage, and ensures reliable locking even under vibration. Its integrated washer eliminates missing parts and misassembly, making it ideal for high‑speed automatic production lines. With multiple material and finish options, our Washer Head Machine Screw offers unmatched versatility for electronics, furniture, lighting, and industrial applications.

One‑Piece Washer Head Design

The biggest advantage of this screw is the one-piece Washer Head design. The washer is integrated with the screw head, so you don’t need to use extra separate washers. Compared with ordinary pan head screws, the built-in washer provides a much larger contact area. It distributes pressure evenly during tightening, so it won’t dent or damage plastic, wood, painted surfaces and other delicate parts. It also resists vibration very well, effectively preventing the screw from loosening or falling off during long-term use. Most importantly, the integrated washer avoids missing parts or wrong installation. It works perfectly on automatic assembly lines without jamming, which greatly improves your production speed and reduces defective assembly.

Wide Applications

Our Washer Head Machine Screw is a universal precision fastener for all light and medium-duty assembly applications. It is widely used for home appliances, switches, sockets, power adapters, electrical housings and internal structure fixing. It also fits all kinds of indoor and outdoor lighting fixtures, furniture cabinets, tables, chairs and board assembly. In addition, it is very popular for plastic products, toys, electronic parts, small machinery, instruments, security hardware and construction decoration hardware. It works smoothly for both manual screwing and high-speed automatic mass production, which makes it a mainstream fastener for electronics, furniture, lighting and light manufacturing industries.

Material Options

We provide multiple material options for this Machine Screw to match different environments, budgets and anti-rust requirements. 201 stainless steel is cost-effective with better rust resistance than carbon steel, ideal for dry indoor assembly. 304 stainless steel is our most popular option. It has stable moisture-proof and oxidation-resistant performance, perfect for kitchens, bathrooms and outdoor ventilated environments with great overall cost performance. 316 stainless steel is high-grade material with excellent salt spray and seawater corrosion resistance, suitable for coastal areas, harsh outdoor conditions, medical equipment and precision instruments. Carbon steel has high hardness and good torsion performance with lower cost, best for dry indoor industrial use with no strict anti-rust demand.

Surface Treatment Solutions

We offer complete professional Surface Treatment solutions for different usage environments and appearance requirements. For carbon steel screws: white zinc and blue white zinc provide basic rust protection with a clean look for standard indoor furniture and electrical products. Color zinc offers better salt spray resistance and longer anti-rust life for humid indoor conditions. Black zinc and black oxide finish are anti-slip and wear-resistant, great for mechanical and precision assembly. Nickel plating has a bright, smooth and premium surface, perfect for exposed decorative parts and high-end electrical products. For stainless steel screws, we provide mirror polishing for a clean high-grade appearance, and passivation treatment to greatly improve corrosion resistance and prevent oxidation and blackening. Custom treatments such as anti-fingerprint finishing are also available.

Quality Control

We implement strict full-process Quality Control for every batch of Washer Head Machine Screw. We inspect raw material purity, hardness and composition before production to avoid low-quality materials. During production, we continuously monitor head forming, cross recess angle, washer flatness, thread precision and concentricity. We strictly reject screws with crooked heads, unflat washers, damaged threads and burrs. For finished products, we test dimension tolerance, torque strength, hardness, salt spray performance and surface quality in batches. This ensures every single screw is consistent in size, stable in locking, no slipping and no breaking. All goods go through final inspection before shipment, keeping the defective rate extremely low and ensuring smooth assembly for your automatic lines with zero jamming and zero rework.
