Product Overview
The Hex Socket Cap Machine Screw is a high-strength fastener featuring a cylindrical head with an internal hex drive, designed for use in high-torque applications. Its precision threads and robust construction make it ideal for heavy-duty structural connections requiring high clamping force.
Key Features
Internal hex drive allows for high-torque installation with Allen keys.
Cylindrical cap head for a low-profile, streamlined appearance.
High-strength construction for heavy-load structural applications.
Precision-machined threads for consistent fit with pre-tapped holes.
Resists stripping under high torque compared to slotted or Phillips heads.
