Head Marking:6 radial lines Metric Grade 8.8 Bolts U-Bolt-It, Inc.Grade 8.8 Bolts are manufactured using medium carbon steel that has been quenched and tempered. Used in railroad equipment, motors, engines and processing equipment, grade 8.8 bolts exhibit good tensile strength and perform well in most environments. They do not perform well in environments that experience temperature extremes. Metric Steel Bolts - Grades and Property ClassesSteel Bolts - Metric Grades ; Steel Bolts - SAE Grades ; For metric bolts strength is according ISO 898 Mechanical properties of fasteners made of carbon steel and alloy steel described by "property classes" with designations 4.6, 4.8, 5.8, 8.8, 9.8, 10.9 and 12.9.

Strength Specifications of Metric Threaded Fasteners

The two figures indicate the tensile and yield strengths of the bolt or screw. In the case of a 8.8 grade bolt the first figure signifies that the Tensile Strength is at least 800MPa. The second figure signifies that the fastener will begin to yield at 80% of the Ultimate Tensile Strength, i.e. at least 640MPa. What Is the Difference Between Plain Grade 8 Bolt & Yellow According to K-T Bolt Manufacturing Inc., Grade 8 bolts "are used in demanding applications such as automotive suspensions. Grade 8 bolts have 6 evenly spaced radial lines on the head." Unlike stainless steel, which is highly resistant to corrosion, steel, however reinforced, will oxidize over time and rust. carbon steel bolt grade 4 8 - quality carbon steel bolt Carbon Steel grade 4.8 5.8 6.8 M16 M20 HDG carriage bolt with fine pitch thread for power Product Description Bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused..

High Tensile Steel Grade 8.8 - 12.9 Fastenright Ltd

High tensile steel bolts and fixings are typically available in grades 8.8 to 12.9. High tensile steel bolts. Grade 8.8 high tensile steel is often referred to as the structural grade for bolts. It is the most common form of high tensile material and is usually stocked in plain finish or zinc. It can be plated in many other coatings.For high tensile steel grade 8.8, a torque wrench will be required for the
