Pro Weld Performance Parts is very proud to offer our Socket Head Screw & Bolt Kits.  These Kits, which are comprised of Select and High Quality Fasteners, offer the confidence and convenience of High Quality Fasteners, organized and combined to provide an easy, low cost way of assembling engine components or replacement hardware, for old worn-out fasteners.

     We offer Kits for every Year & Type of Modular Engine, from the Two Valve Engine to the Three and Four Valve Engines.  Ours kits cover all Major and Minor areas, from oil pan socket head bolt kits, to TPS & IAC socket head screw kits, and every area in-between.  We build all our Custom Modular Engines with our own hardware, and believe you should too!  We are the only company that I know of that offers this service.  You wouldn't expect us or any other engine builder to build you a new high performance or stock replacement engine with worn OEM parts, so why put up with re-using old OEM fasteners, when there is a much better and stronger alternative?  Our Socket Head Fasteners out-perform the OEM stuff hands down.  They are Stronger, Harder, more Durable and made with quality materials that put you and your engine's needs first, not something a Detroit Bean-Counter came up with!  We strive for excellence in all we do, and it's no different with our Socket Head Kits.  We offer most every fastener for all Modular Engines, and if there is something you need but don't see listed, give us a call and we'll get it for you.  Try our new and complete line of Socket Head Screws and Bolts, I think you'll like them.

Ford 4.6L Socket Head Stud Kits

     We use only the Highest Grade Metric Fasteners.  Our Socket Head Bolt Kits are comprised of the Finest Grade 12.9DIN, Black Oxide Fasteners, that are the equivalent to our Grade 9-10 Fasteners.  This is Military spec grade hardware, that will keep your engine parts together, without worry or sacrifice.  While cheaper than the Threaded Stud Kits, these Socket Head Kits give up nothing in performance or strength.  Sometimes it's just not practical to use a stud, and if that is the case, then you should be using these.  We use only the highest quality metric hardware, both in the Socket Head Screws and in the Heavy Duty Washers that come with them.    The Washers, are special 1010 Cold Rolled, Case Hardened, Black Oxide Steel Washers. They have a  Thickness Tolerance of +/- 0.050 In!  Rockwell Hardened to N Scale 80 , gives you  excellent Load Distributing Characteristics that will spread the clamping forces out over a much wider area.  These Washers will not Bend or Distort, nor wear down, which allows for excellent torque retention and strength.

            Our new Selection of Stainless Steel fasteners for the Ford Modular Engines is offered to the enthusiast that not only wants quality hardware, but wants it to shine as well.  Our Stainless Steel Socket Head Screws are Grade A2 18-8 Stainless and will provide a great and flashy way or mounting your engine accessories for a very long time.

     Don't make the mistake of comparing any of our kit components to "Hardware Store" hardware.  We don't use common or cheap fasteners, in-fact, all our fasteners, both Socket Head and Threaded Studs, are special built, special order pieces.  Where the common low grade 2 or 5 washers cost a mere 0.02 to 0.04 each, the Hardened, Black Oxide Super Washers we use are some 25 to 35 times more expensive than those, with a couple of our kits climbing to over 75 times more expensive!  Our fasteners are excellent up-grades from factory hardware and were engineered for both the race and the street user.  Many of the Kits we have, especially the 03-04 Cobra and  99-04 Cobra & Mach1 hardware, are the only practical way to replace the old factory hardware with new components.  Ford's stock is all but dried up for many of these applications.

     We have gone to great lengths to provide you, our customer, with the very best in Fasteners for your High Performance Engine.  Every Step, we sought to improve on the system, and this is why, where we could, we used longer length bolts and screws.  Where the threads allowed, we maximized the thread length, to insure the highest amount of threads holding that piece together.  Areas like the Main Bearing Cap, Side Bolts, and the Cam Shaft Bearing Caps, we were able to increase the thread count by some 5-10mm, enough to double the holding capacity in many items!  This is the Performance you and your engine both deserve and can expect from Pro Weld.
