Product Description
The Seatbelt Planet Shoulder Loop Bolt is the anchor bolt used to mount a shoulder belt loop or other belt anchor. It is a small part, but a secure installation depends on the right bolt.
Specifications
- 7/16 inch bolt, 1.5 inch long
- Sleeved diameter below the bolt head measures 9/16 inch
- 20 fine threads
- Clear zinc plated
What It Does
The bolt passes through the shoulder loop or belt anchor and threads into the mounting point in the vehicle, usually on the pillar or a reinforced plate. The sleeved section under the head lets the loop pivot freely so the belt can move with the passenger.
Checking the Mounting Point
Before installing any seat belt hardware, make sure the threads in the body or plate are clean and undamaged and the surrounding metal is solid. Repair rust or damaged metal before installing.
When to Replace
Reusing an old, rusty or stretched bolt is a false economy. A new, properly plated bolt costs little and makes sure the anchor is as strong as the belt.
Matching Your Belt
Check that your belt's anchor or loop fits the 9/16 inch sleeve and that your mounting point uses 7/16-20 threads before ordering. If you are unsure, contact us with your belt and vehicle details.
Tightening
Tighten the bolt securely to the torque your vehicle or belt maker specifies, and recheck it after the first few drives.
Part of a Complete Installation
A seat belt is only as strong as its anchors. Use correct bolts, washers and reinforcement plates where your vehicle calls for them.
Clear Zinc Plating
The clear zinc finish resists corrosion, which matters for a bolt that may sit in a damp pillar or floor for years.
Ordering Spares
If you are installing belts in several seating positions, order a bolt for each loop or anchor that needs one.

Getting Help

Inspect Regularly
Check belt anchors for tightness when you service the car, especially after interior work that may have disturbed them.
Retrofits
When adding shoulder belts to a car that never had them, the upper anchor location must be strong. Use a proper reinforcement plate behind thin sheet metal.
Thread Check
Run a tap through old threads to clean out rust and debris before installing a new bolt, so it seats fully and tightens properly.
Using Washers
Where your belt or loop calls for spacers or washers, reuse or replace them so the loop pivots freely on the sleeve.
