🔧 Product Description

Genuine Volvo Penta stud weighing 0.025 kg and listed for 12 applications on the D series. No length or thread is published, and both the 50 mm stud 953069 and 953251 carry the same weight, so the part number and the D series fitment are what identify it.

🔌 Function

Screws into the casting to present the fixed male thread the clamping nut tightens against.

⚠️ Common Signs of Failure

• Stud comes away with the nut
• Thread corroded or pitted
• Stripped thread at the nut end
• Sheared at the casting face

🛠️ Service Notes

• Clean and chase the female thread before fitting so the stud can pull down square and to full depth
• Screw studs in with a proper stud installer or the double-nut method; gripping the plain shank with pliers or self-grips scores it and the nut will never seat or torque correctly afterwards
• Screw the stud home until it seats as the manual for your engine describes, and no further — a stud wound in hard to cure a slack thread will simply split the casting
• Renew studs that are stretched, necked, bent or corroded rather than reusing them; exhaust and manifold studs in particular are cheap next to the work of extracting a broken one
• Tighten the nuts to the torque figures and in the sequence given in the workshop manual for your engine, and where a stud passes into an oil or coolant space seal it as the manual specifies
