#4-40 x 1/2" Truss Head Machine Screws, Phillips Drive, Fully Machine Thread, 18-8 Stainless Steel 304, Bright Finish, Pack of 100

Key Specs: #4-40 x 1/2"; Head Style: Truss (Low-Profile Wide Head); Head Diameter: 0.241" – 0.257" (6.12 – 6.53 mm); Head Height: 0.059" – 0.069" (1.5 – 1.75 mm); Drive Type: Phillips #1; Package: 100 PCS Made from corrosion-resistant 304 stainless steel, providing superior strength and long-lasting performance in humid, outdoor, or chemically exposed environments. It withstands the elements without rusting, ensuring reliability with minimal maintenance. Widely Compatible Phillips Drive for Easy Installation: The standard Phillips #1 drive offers universal compatibility with the vast majority of cordless drills, impact drivers, and hand screwdrivers. This allows for quick, efficient, and tool-stripping resistant installations in both professional and DIY settings Ideal for Small Electronics & Hobbyist Projects: This tiny truss head screw is perfect for assembling portable electronics, drone frames, scale models, and light fixtures. Its wide head securely fastens thin plastic or metal panels without pull-through, while the 304 stainless steel offers corrosion protection for sensitive internal components Low-Profile Truss Head Design with Wide Bearing Surface: The unique truss head provides a larger diameter and bearing area than a standard pan head, while maintaining a lower profile. This design distributes clamp force more effectively, reduces the risk of pull-through in softer materials (like plastics or thin sheet metal), and creates a neat, finished appearance Upgrade your projects with our professional-grade 304 Stainless Steel Truss Head Machine Screws. Designed for applications that demand a secure hold, a clean finish, and exceptional durability, this series combines the best attributes of traditional head styles into one versatile fastener. Why Choose a Truss Head? The Balanced Advantage Vs. Pan Head: Unlike a standard pan head, our truss head features a significantly wider bearing surface diameter at a lower profile. This provides superior resistance to "pull-through" on soft or thin materials like sheet metal, plastic, and fiberglass, distributing clamp force more effectively to prevent damage. Vs. Countersunk (Flat Head): Unlike a flat head screw that requires a precise conical countersink hole to sit flush, the truss head installs easily on flat surfaces. It offers a neat, low-profile finish without the need for specialized drilling, saving time and simplifying assembly.
