High Strength Alloy Steel GB37 T Head Bolt Grade 10.9 for Machine Tool Fixtures
GB37 T-slot bolts are precision-engineered fasteners designed in accordance with Chinese National Standard GB/T 37-1988. Featuring a T-shaped head that embeds securely into T-slots, these bolts provide strong, non-rotating connections in machinery, fixtures, and structural applications.
Key Features
Easy Installation: T-shaped head design enables direct embedding into T-slots with automatic positioning, eliminating the need for additional locating devices
Stable & Secure Connection: Increased contact area between the T-head and slot provides superior resistance to tension and shear forces, preventing relative displacement between components
Wide Specification Range: Available from M5×16 to M48×1000 to accommodate diverse slot sizes and application requirements
Strong Versatility: As a national standard bolt, GB37 T-bolts are interchangeable with matching nuts, washers, and other standard fasteners
