Quest Gasket supplies alloy steel stud bolts in 3/8-inch through 4 3/4-inch diameters and to any length. Our tap-end stud bolt combines a cold forming process with a superior design incorporating a thread shoulder for uniform depth of engagement.

SPECIAL COATINGS
We also can furnish a wide range of special coatings to prevent corrosion. Whether it’s cadium, zinc plating, Teflon and Xylan flurocarbon or other coatings, all protect our products from conditions and environments that uncoated bolts can’t withstand.

* Ferritic Steel Grades L7 and L7M together with Austenitic Grades B8 and B8M are normally stocked for immediate shipment, with the other Grades available on special order. Grade L7 is normally used to -50° F without Charpy Test and to -150° F with a Charpy Test. Grade L7M is normally used in H2S service with a required Charpy Test at -100° F. All of the Austenitic steels listed above may be used to -325° F without a Charpy Impact Test and at lower temperatures with the requisite tests.
