This article delves into the key features of vacuum screws, including their materials, venting designs, and surface coatings. DGVIFORT is dedicated to providing the most suitable fasteners for your vacuum projects. Whether you need a standard product or a custom solution, we are your trusted partner.

We specialize in the custom manufacturing of high-performance aluminum screws, offering a diverse selection of materials including 6061, 6001, 7075, and 5052 aluminum alloys. Our comprehensive in-house capabilities encompass expert material selection, precision heat treatment (T4, T6), CNC machining, and various surface finishes. These lightweight, strong, and corrosion-resistant fasteners are engineered for critical applications in aerospace, automotive, electric vehicles (EVs), electronics, and marine industries. We provide end-to-end solutions, producing parts strictly to customer drawings and specifications.

Our captive screws (non-loss screws) are permanently retained panel fasteners designed for electronics enclosures, server racks, and aerospace applications. They prevent loose hardware, streamline assembly/maintenance, and enhance product reliability. We offer extensive customization in materials, finishes, and designs, with free engineering samples available for qualification.

Our custom CD pattern screws are precision-engineered fasteners designed for high-end electronics. With CNC-machined concentric texture and strict tolerance control, we provide OEM, ODM, and CDM services with free samples and reliable mass production.

Precision-drilled Vented Hex Head Screws eliminate air and fluid entrapment in blind tapped holes. Made from corrosion-resistant 18-8 Stainless Steel, their through-hole design significantly reduces vacuum pump-down time and prevents pressure buildup, making them crucial for high-vacuum, scientific, and fluid power systems.

A precision CNC machined push rod made from ASTM 12L14 steel with matte nickel plating, engineered for industrial actuator applications requiring exceptional concentricity, fine surface finish, and ±0.01 in. tolerance control.

Our insert screws for CNC tool holders and torx screws for turning inserts are precision-engineered for secure clamping and reliable positioning of carbide inserts. Made from high-quality alloy steel or stainless steel, these screws deliver excellent strength, wear resistance, and precision fit. Head type, material, surface coating, and hardness can all be customized to meet your machining requirements. Send your drawings for quotation and sample verification.

High-strength molded-in threaded inserts including blind, thru-threaded and knurled types for injection-molded components.
