Detailed Engineering Specifications

Engineered for reliability and performance, this M17 x 48mm hex head cap screw is precision manufactured from high-grade brass, offering excellent tensile strength and inherent corrosion resistance, particularly against galvanic corrosion in marine or humid environments. The M17 thread pitch ensures a strong mechanical interlock with compatible tapped holes or nuts. With a substantial 24mm head width, it provides ample surface area for torque application with standard wrenches, facilitating secure tightening and preventing deformation under load. Its inherent non-magnetic and non-sparking characteristics make it suitable for sensitive electrical or hazardous area installations.

Installation Procedure

1. Select the appropriate M17 tapped hole or nut. Ensure threads are clean and free of debris. 2. Insert the hex head cap screw, engaging the threads smoothly by hand for at least two full turns to prevent cross-threading. 3. Tighten the screw using a calibrated torque wrench to the manufacturer's recommended torque value for M17 brass fasteners, ensuring a secure but not over-tightened connection.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force, leading to thread stripping or screw breakage.Always use a calibrated torque wrench and adhere to recommended torque specifications for brass fasteners.
Cross-threading the screw due to improper alignment during initial engagement.Start engaging the threads by hand for at least two full turns to ensure proper alignment before applying any tool.
Using the wrong size wrench, which can round off the hex head and prevent proper tightening.Ensure a snug-fitting wrench of the correct size (24mm) is used for tightening.

Common Applications

  • Marine hardware and fittings
  • Electrical enclosures and grounding
  • Chemical processing equipment

⚠️ Engineering Warnings

  • Brass is a softer material than steel; avoid over-tightening to prevent damage to threads or the fastener.
  • While corrosion-resistant, brass can react with certain aggressive chemicals. Consult compatibility charts for specific applications.
