Cap Screws

Custom fasteners Manufacturer

Stainless steel low-profile socket cap screws

Type: Hexagon head cap screws, self-locking screws, nylon patch screws

Material: Stainless steel

Finish: Passivated


Standard: Inches, Metric


Advantage of Low profiles socket cap screws

  • socket cap screws can Improve the locking force and thread accuracy to prevent loosening (the combination of high locking force and 5g/6g thread accuracy can effectively solve the problem of screw loosening)

  • Low profile is 15% smaller than standard scoket screw,Reduce the screw size to achieve the locking effect required by the design (with high-strength small-sized bolts, the locking force of the original large-sized bolts can be obtained, and the locking effect required by the design can be achieved, so as to solve the problem of “locking” is caused by “tight design” to the greatest extent. and meets the requirements of lightweight design.)

  • Low profile socket cap screws with High strength can improve wear resistance (by increasing the surface hardness of the product, the wear of the thread and the supporting surface can be reduced, the wear resistance of the screws can be improved, and the high axial force can make the supporting surface and the object close to each other and prevent leakage. The effect is remarkable.)
  • Can be used multiple times (increasing the surface hardness can improve the surface deterioration caused by repeated use, and has the advantage of multiple uses.)
  • Delayed fracture resistance (use special alloy steel to reduce the content of harmful elements such as p, s and increase the content of Mo, reduce grain boundary segregation, strengthen grain boundaries, and use Mo, V secondary hardening carbides to improve the recovery of steel. Fire temperature and strength, control carbide state and distribution, and improve the delayed fracture resistance of products.)
  • Good anti-destructive performance (special heat treatment process makes the product have more excellent anti-destructive performance
