Product Core Advantages
Square Neck Anti-rotation Design
Built-in square neck structure locks tightly in T-slots, effectively preventing bolt rotation during tightening. It provides stable clamping force without slipping, greatly improving assembly accuracy and efficiency for heavy-duty repeated clamping scenarios.
Reinforced Thick T-head for Heavy Load
Widened and thickened T-head increases compression area, disperses heavy load pressure, avoids workpiece deformation and bolt fracture. Higher shear resistance and tensile strength than ordinary T-bolts, specially designed for heavy industrial working conditions.
Full Heavy-duty Size Coverage
Complete sizes from M6 to M48, sufficient stock for large heavy-duty specifications. Standard metric coarse thread ensures strong universality and interchangeability with standard T-slot workbenches and fixture accessories.
Multi-grade & Multi-finish Options
Multiple strength grades and surface treatments cover general fastening, heavy-load compression and anti-corrosion working scenarios. Suitable for indoor dry workshops, humid processing environments and outdoor heavy equipment assembly.
Grade Selection Guide
Grade 4.8 Black Oxide Bolt (Economical Type)
Cost-effective conventional grade with black anti-rust treatment, suitable for light-duty tooling, small mold plate and general equipment base fixing.
Grade 8.8 Zinc Plated Bolt (Practical Anti-rust Type)
Reinforced mechanical strength with electro-galvanized anti-corrosion finish, ideal for humid workshop tooling fixtures and medium-load mold clamping.
Grade 10.9/12.9 High-strength Bolt (Heavy-duty Type)
Quenched and tempered high-grade steel with excellent fatigue resistance and tensile strength, perfect for large stamping molds, heavy machine tools and steel structure foundation fixing.
Stainless Steel Bolt (Corrosion-resistant Type)
304/316 stainless steel material, anti-oxidation and anti-corrosion, suitable for chemical, food, humid and outdoor harsh working environments.
DIN186 vs DIN787 Difference
DIN186 Square Neck T-Bolt: Equipped with anti-rotation square neck and thick reinforced head, high strength grade, designed for heavy-load, high-precision and repeated clamping working conditions, widely used in heavy machinery and large mold industries.
DIN787 T-Slot Bolt: Lightweight structure without square neck, low load capacity, only suitable for light-duty ordinary tooling assembly, unable to bear heavy industrial compression load.
Production Process
High-quality Raw Material Selection: Adopt qualified carbon steel and stainless steel bars to ensure stable mechanical properties and load-bearing capacity.
Automatic Cold Heading Forming: Integrated forming of T-head and square neck with dense structure, no cracks or defects for stable overall performance.
Precision Thread Rolling: Standard 6G thread with full gauge inspection to ensure smooth assembly and tight meshing without slipping.
Head Finishing & Deburring: Flat and smooth compression surface ensures uniform stress and stable fitting.
Professional Anti-corrosion Treatment: Multiple surface processes to adapt to different indoor and outdoor working environments.
Strict Batch Quality Inspection: Comprehensive testing of size, thread, hardness and tensile force to guarantee consistent batch quality.
Application Industries
Machine Tool Processing: CNC machine tool workbench T-slot fixture clamping and workpiece positioning.
Mold Manufacturing: Large stamping mold and injection mold plate fastening and base positioning.
Heavy Machinery Equipment: Heavy equipment frame, base fixing and large tooling platform locking.
Steel Structure Engineering: Light steel structure base and equipment bracket compression positioning.
Automation Equipment: Automation tooling fixture and assembly board high-strength locking.
Precision Machinery: Stable compression and positioning of testing equipment and experimental platforms.
