Hammer Head T Bolts Square Head Screws Black 8.8 High Tensile Steel M8 M10 - M36

Hammer Head T Bolts Square Head Screws Black 8.8 High Tensile Steel M8 M10 - M36

‌Material Features‌

‌High-Strength Steel‌: Made of premium carbon steel (45# or 35CrMo), heat-treated to Grade 8.8 (Tensile strength≥800MPa, Yield strength≥640MPa). Zinc-plated/Dacromat coated with 72hrs salt spray resistance.

‌Precision Forming‌: Cold-forged with T-slot dedicated molds, smooth head-shank transition reduces stress concentration. Thread tolerance: 6g (GB37 compliant).

‌Optimized Slot‌: Standardized T-slot width (8mm/10mm) and depth compatible with ISO/DIN clamping plates, eliminating on-site modification.

‌Efficiency Benefits‌

‌Quick Positioning‌: T-head slides directly into machine tool slots, 60% faster installation vs. conventional bolts.

‌Vibration Resistance‌: Preload torque up to 40N·m (M12 tested), maintains clamping force under dynamic loads.

‌Broad Compatibility‌: Fits EU/CN T-slots (e.g., HAINBUCH/SCHUNK systems), high interchangeability.

‌Usage Warnings‌

  ‌Critical Notes‌:

Never hammer the head! Use dedicated wrenches (torque wrench recommended);

Inspect thread wear every 500 operating hours;

Pair with stainless washers in humid environments.

‌Typical Applications‌

  CNC machine fixtures (milling centers, lathes)

 Automation line module alignment (robot base plates)

  Solar mounting system & steel structure connections

  Heavy equipment access panel fastening (with threadlocker)
