🇺🇸 Memorial Day at Hex 6 🇺🇸
Today, as a proud veteran-owned business, Hex 6 pauses to honor the brave men and women who made the ultimate sacrifice for our country.
In remembrance of our fallen heroes, Hex 6 Diesel Services will be closed today as we reflect on the freedoms we have because of their courage, service, and selflessness.
We would also like to take this opportunity to thank the Lord for the soldiers and military families who have sacrificed so much in service to our nation. We pray for comfort, peace, and gratitude as we remember those who gave everything.
“Greater love has no one than this: to lay down one’s life for one’s friends.” – John 15:13
Today, we honor. We remember. We are forever grateful. ❤️🤍💙

When the miles stack up… so does the wear.
This FedEx truck rolled in with a rear axle housing leaking oil—and after inspection, we found the housing had cracked right at a factory weld. With over 1 MILLION miles, even the toughest components can give way.
Our team got to work:
✔️ Cleaned and prepped the damaged area
✔️ Performed multiple weld passes for strength and durability
✔️ Pressure-tested and verified the repair
We followed up with the customer last week… no more leaks and back on the road 💪
At Hex 6 Diesel Services, we don’t just fix problems—we help prevent downtime and keep your operation moving.
