APM HEXSEAL performs testing to verify fit and function of products produced. (“APM HEXSEAL”) is a manufacturer of environmental sealing solutions. 316 stainless steel has the highest degree of corrosion. Testing is done to various bolts and metal plates, torqueing them until the point of failure. Contact BUMAX sales representative for more information.APM HEXSEAL Corp. It is in the 18-8 family of stainless steels and is included in most. Torque values are calculated giving way to preliminary data tables. ![]() 235-3706: Chevrolet Big Block Dart aluminum head exhaust bolts only, (8 pieces). BUMAX® Ultra is an advanced engineering grade and close technical support is provided by BUMAX customer projects in order to develop the desired end solution. head bolt torque for A mark 6 502 with steel heads. These 18-8 stainless steel screws have a hardened steel drill point to penetrate steel and are coated to increase corrosion resistance. All BUMAX Ultra fasteners are custom made to meet the requirements of individual applications and can be delivered with different mechanical properties, sometimes with even higher strength than class 159. 18-8 Stainless Steel Hex Head Drilling Screws with Hardened Steel Tip for Metal. ³Typical strength level for BUMAX® Ultra “The world’s strongest stainless steel fastener” is 159 (Tensile strength min 1500 MPa/ Yield strength min 1350 MPa). They have a thread locker to prevent loosening from vibration. They are stronger than Grade 8 steel screws and are nearly two and a half times stronger than stainless steel thread-locking screws. 18-8 stainless steel pan head screws have good chemical resistance and may be mildly magnetic. With a tensile strength of 170, 000 psi, these alloy steel screws are among the strongest we carry. ²The Preload applied kN is calculated as 65% of Rp0.2 but in practice the value can be expected to vary between 50-80% (+/- 23%). Alloy Steel Thread-Locking Socket Head Screws. Torque Values Stainless Steel Bolt Table Chart. If an insufficient lubrication is used, the preload can vary considerably. 4 stripped oil pan bolt OIL PAN TORQUE SPECS SEQUENCE CHEVROLET CRUZE SONIC. Bolt Size: 18-8 Stainless Steel : Brass: Aluminum 2024-T4: 316 Stainless Steel: Nylon: 2 - 56: 2.5: 2.0: 1.4: 2.6: 0.44: 4 - 40: 5.2: 4.3: 2.9: 5.5: 1.19: 4 - 48: 6.6: 5.4: 3.6: 6. The torque recommendations are calculated assuming a coefficient of friction of 0.14, which requires a good quality lubricant. ![]() ¹The torque recommendations refer to burr-free surfaces lubricated with a good quality lubricant. If considerable thread galling problems occur when assembling, please contact our technical service.īumax Hard Taptite, thread forming screws Maximum torque: 2,280Nm ( 123) (or 117) Mean torque if scatter is +23 2,280 / 1.23 1,854 Nm. MoS 2 lubricant or similar is recommended in unfavorable assembly conditions. ![]() Punching screw-driving machines should not be used. When assembling stainless steel joints, a very low revolution screw-driving machine is required, or the screws should be tightened by hand. ![]()
