Detailed Engineering Specifications

Precision-manufactured to tight tolerances, this M15x97mm hex head cap screw exhibits superior dimensional accuracy for consistent engagement. Constructed from solid brass (often alloyed for enhanced strength and machinability), it provides excellent resistance to galvanic corrosion, making it ideal for marine, chemical, and electronic applications where dissimilar metals are present. The substantial M15 thread diameter and 97mm length offer robust load-bearing capacity. The 28mm head width ensures ample surface area for torque application with standard tooling, preventing fastener deformation under load.

Installation Procedure

1. Clean both the screw threads and the mating tapped hole or nut to remove any debris or protective coatings. 2. Apply a suitable thread lubricant or anti-seize compound if recommended for the specific application to ensure smooth installation and prevent galling. 3. Engage the screw by hand to start the threads, ensuring proper alignment to avoid cross-threading. 4. Use an appropriately sized wrench or socket to tighten the hex head to the required torque specification, applying steady pressure.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Over-tightening the brass screw, leading to thread stripping or head deformation.Always adhere to the manufacturer's recommended torque specifications for the fastener and mating material. Use a calibrated torque wrench for accuracy.
Using the wrong size wrench, causing slippage and potential damage to the hex head.Ensure the wrench or socket fits snugly on the hex head to provide maximum grip and prevent cam-out.
Installing the screw into a dirty or damaged tapped hole or nut, causing thread damage and a weak connection.Thoroughly inspect and clean the mating threads before installation. Chase or re-tap if necessary.

Common Applications

  • Marine hardware and fittings
  • Electrical and electronic enclosures
  • Chemical processing equipment
  • Decorative and architectural fixtures

⚠️ Engineering Warnings

  • Brass is a relatively soft metal; avoid excessive force or impact that could damage the threads or head.
  • While corrosion-resistant, brass can still react with certain aggressive chemicals. Verify compatibility for your specific environment.
