Ball Plunger Grub Screws are precision-engineered spring-loaded screws featuring a high-quality steel or stainless steel ball seated within a threaded body. Designed specifically for accurate positioning, indexing, and controlled pressure applications, these screws utilize an internal spring mechanism to deliver consistent force, enabling reliable engagement and disengagement between mechanical components. Constructed from stainless steel, carbon steel, or brass bodies combined with hardened steel or stainless steel balls, the product offers robust resistance to wear and corrosion. Available in both metric and inch thread types (UNC/UNF), and compliant with DIN 438 and ISO standards, these ball plunger grub screws cater to customizable application needs with light, medium, and heavy spring force options. They are vital components in jigs, fixtures, molds, indexing mechanisms, detent systems, and door latches, widely employed across automotive, aerospace, tooling, and machinery manufacturing industries for enhanced precision and operational reliability.
