HYDROGEN EMBRITTLEMENT
WHAT IS HYDROGEN EMBRITTLEMENT?
When atomic hydrogen enters steel , it can cause a loss in ductility or load carrying ability or cracking (usually as
sub-microscopic cracks), or catastrophic brittle failures at applied stresses well below the yield strength. The Hydrogen
Embrittlement caused failure, the actual breaking of the component into two or more pieces. The fracture is delayed.
Problems occur when least expected. Sometimes it occurs within hours after the tensile load is applied; sometimes
not for months, but seldom years. But when it happens, it’s sudden, with no advance warning or any visible signs of
imminence, Failures occurring in service are serious and costly, sometimes catastrophic.
Hydrogen embrittlement is associated with fasteners made of carbon and alloy steels. It is only usually expected to be a
risk for higher tensile fasteners with hardness above 320HV. It is caused by the absorption of atomic hydrogen into the
fastener’s surface during manufacturing and processing, particularly during acid pickling and alkaline cleaning prior
to plating, and then during actual electroplating. The deposited metallic coating entraps the hydrogen against the base
metal. When load or stress is applied the hydrogen gas migrates towards points of highest stress concentration. Pressure
builds until the strength of the base metal is exceeded and minute ruptures occur. Hydrogen is exceptionally mobile and
quickly penetrates into any recently formed cracks, lesions or material surface discontinuities, which become high stress
areas.
HOW TO MINIMIZE THE RISK OF HYDROGEN EMBRITTLEMENT?
Though the experts recommend various preventive measures, there is no known guaranteed process to eliminate
Hydrogen embrittlement 100%. When embrittlement failures do occur, they will usually only affect 2-3% of the
components. The embrittling process is a random effect, and the de-embrittling process can be regarded similarly.
Whilst prediction is difficult, if the following preventative actions are applied, then the risk should be minimised.
1. Mechanically clean the products if possible.
2. Mechanically plate high strength components.
3. Avoid any embrittling process if possible.
4. Use stringent baking control.
The rapid transfer into the baking oven possibly reduces the opportunity for harmful hydrogen to begin its inward
migration. It is the prevention of inward migration that will reduce the probability of embrittlement failure.
PREVENTATIVE ACTIONS TO REDUCE RISKS IN PLATING.
Last but not the least is to Consider alternative surface coatings like, Geomet, Delta Tone, Delta Seal, Magni, Mechanical Zinc plating.
They will cost more than normal plating.

SOCKET HEAD CAP SCREW
FIRM FAITH ON CAPARO SOCKET HEAD CAP SCREW
While using Fasteners all are aware the importance of fasteners technology. Higher Pressure higher Stress and
higher Speed demand Strong & reliable joints and its give reliable fasteners only.
This is the reason Industry is using more and more Socket Head Cap Screw. The Strongest threaded fasteners
have the extra strength and fatigue resistance required for complete reliability in high strength fastening.
1. High life Rolled Threads are more uniform and have closer tolerance because CAPARO roll thread dies
and techniques produce smoother surface and better size control. Fully formed radius root run out increase
fatigue life of threads by reducing stress concentration and avoiding sharp corner where failures may start.
2. Socket Depth: - Controlled Socket depth gives optimum wrench engagement, permit full tightening without
cracking.
3. Specially formed Head: - Controlled head forging forms uniform grain flow without crack flow lines. It makes
Head stronger & prevents failure in vital fitted area.
4. Heat Treatment: - Heat Treatment is tailored to suit the specific chemistry of every lot of Steel. Atmosphere
controlled furnace eliminate possibilities of surface carburization or decarburization to ensure maximum
strength and toughness.

Measurement styles of Hex Head
MEASUREMENT STYLES OF HEAD
Diameter of all bolts is measured as the outside of major diameter of the thread. The length of a headed bolt
is measured from the largest diameter of the bearing surface of the head to the extreme end of the point in
a line parallel to the axis of the bolt. For example, square or hex head bolts are measured from under the
head to the end of the bolt; a bolt with a countersunk head is measured overall. The point of a bolt is always
included in the measured length. Headless fasteners such as studs are measured overall, including points,
except for continuous-thread alloy studs made to ASTM Specification A193. This type is measured from first
thread to first thread.

HIGH STRENGTH FRICTION
GRIP BOLTS (STRUCTURAL)
‘Caparo‘ High Strength Friction Grip( Structural) Bolts, Nuts and Washers in Friction Grip Joints.
Bolted joints are one of the most common elements in construction and machine design. They consist of
fasteners that capture and join other parts, and are secured with the mating of screw threads.
There are two main types of bolted joint designs. In one method the bolt is tightened to a calculated clamp
load, usually by applying a measured torque load. The joint will be designed in such a way that the clamp
load is never overcome by the forces acting on the joint (and therefore the joined parts see no relative
motion).
This type of joint design provides several properties:
• Greater preloads in bolted joints reduce the fatigue loading of the fastener.
• For cyclic loads, the fastener is not subjected to the full amplitude of the load; as a result, the fastener’s
fatigue life can be increased or—if the material exhibits an endurance limit—extended indefinitely.
• As long as the external loads on a joint don’t exceed the clamp load, the fastener is not subjected to any
motion and will not come loose, obviating the need for locking mechanisms.
• The other type of bolted joint does not have a designed clamp load but relies on the shear strength of
the bolt shaft. This may include clevis linkages, joints that can move, and joints that rely on a locking
mechanism (like lock washers, thread adhesives, and lock nuts
• The clamp load, also called preload, of a fastener is created when a torque is applied, and is generally a
percentage of the fastener’s proof strength; a fastener is manufactured to various standards that define,
among other things, its strength and clamp load.
• When a fastener is tightened, it is stretched and the parts being fastened are compressed; this can be
modeled as a spring-like assembly that has a non-intuitive distribution of strain. External forces are
designed to act on the fastened parts rather than on the fastener, and as long as the forces acting on the
fastened parts do not exceed the clamp load, the fastener is not subjected to any increased load.

22. 22
• However, this is a simplified model that is only valid when the fastened parts are much stiffer than the
fastener. In reality, the fastener is subjected to a small fraction of the external load even if that external
load does not exceed the clamp load. When the fastened parts are less stiff than the fastener (soft,
compressed gaskets for example), this model breaks down; the fastener is subjected to a load that is the
sum of the pre-load and the external load.
