Question 1

What is PPAP and what level do you provide for automotive fasteners?

Accepted Answer

PPAP (Production Part Approval Process) is the automotive quality documentation standard. PGS Fasteners provides PPAP Level 3, which includes dimensional reports, material certifications, process capability (Cpk), FMEA, and control plans — standard for Tier-1 OEM supplier qualification.

Question 2

What grade of bolt is used in engine assembly?

Accepted Answer

Engine assembly bolts are typically grade 10.9 (high-tensile alloy steel) for critical joints requiring high clamping force. Cylinder head bolts may be torque-to-yield (TTY) grade 10.9+. External accessory mounts use grade 8.8.

Question 3

Do you supply fasteners for electric vehicle (EV) platforms?

Accepted Answer

Yes. EV platforms require fasteners with aluminium-compatible coatings (to prevent galvanic corrosion), precision tolerances, and weight-optimised designs. We supply A2-70 stainless and zinc-nickel coated fasteners for EV battery packs and power electronics mounts.

Question 4

What is the dimensional tolerance for automotive fasteners?

Accepted Answer

Automotive fasteners conform to ISO 4759 tolerance class A (tight) for critical joints. Dimensions are controlled to ±0.05mm on critical features with 100% gauging on safety-critical parts.
