Made from aircraft grade titanium 6AL-4V (grade 5), the outstanding benefits are that we roll the threads to produce greater fatigue strength and reduce galling.

These bolts are in excess of 120,000psi ultimate tensile strength, suitable to replace both Grade 5 and Grade 8 steel bolts. We offer Drilled Flanged Hex Head Bolts, Flanged Hex Head, Tapered Socket Cap, Countersunk Bolts, Dome Head Bolts, Nuts and Washers – from 3mm to 12mm.

  • Shear Strength: 330MPa (47.9 x 103psi)
  • Ductility: 10% elongation at break
  • Poisson's Ratio: 0.33
  • Hardness: 150 Brinell
  • Strength-to-Weight Ratio: 185 kNm/kg

Manufactured from 7075T6 aluminium, and suitable for use in all non-safety critical areas, all products are available in a choice of black, blue, gold, orange, purple, red and silver. During manufacturing, the head is cold formed and the shank thread rolled.

The anodising involves chemically brightening and colour anodising to between 8 and 12 microns thick. We offer Drilled Flanged Hex Head, Socket Cap Bolts, Countersunk Bolts, Dome Head Bolts, Nuts and Washers – from 3mm to 10mm.

We also stock a weight reducing Drilled Flanged Hex Head Bolt with a Potassium Dichromate finish, which is excellent for Marine and Mining applications. This finish can be added to any product in the aluminium range.
