Hex Bolts (cold/hot forged) DIN
931 / Din 933 |
|
 |
| |
Hexagon Bolts are created to DIN 931, DIN933 and are
a threaded fastener with a hexagon-shaped head
that is usually fixed with a spanner or socket tool.
Hosting a machine thread, these bolts are suitable for
use with either a nut or within a pre-tapped hole.
Materials can include various grades of steel, including
Grade 5 (5.6), Grade 8 (8.8), Grade 10 (10.9) and Grade
12 (12.9) with zinc plating, zinc and yellow,
galvanising or self colour. They are also available in
A2 and A4 stainless steel, with other materials
available to order.
As standard, they are available in sizes from M3 to M64,
with non-standard sizes and threads – such as UNC, UNF,
BSW and BSF – all possible to order. |

Socket head screws DIN 912 /
ISO4014 |
|
 |
| |
Hexagon socket head cap screws, DIN 912 These are
classic metric screws with cylinder head and hexagon
socket also known as SHCS. All these screws are 8.8 and
are zinc-plated as a protection against corrosion.
Socket Cap Screws to DIN 912 are often referred to as
Allen head bolts.
They host a hexagonal recess and are driven using an
insert bit or a hex wrench, making the screws more
efficient than the slotted screw products as the hex
socket drive has more resistance to cam out and can be
used with power drivers to enable faster installation.
Higher torque is able to be achieved with the use of
this socket head too. |

Button Head Screws ISO7380-1 /
Button Head Screws with Flange ISO7380-2 |
|
 |
| |
Screw with inward hexagonal grip and a rounded head
and a flange. The flange substitutes a loose washer.
Flange button socket screws Fasteners are protective
fasteners which provide the assembly with structural
support as well as a visually appealing look. It
protects the components around it from damages like
scraps and unintentional cuts. Another advantage of
these screws is the large under head bearing surface -
this eliminates the need for washers. It could also be
considered as a built-in washer. These screws are fully
threaded to provide its users with grip and accurate
positioning.
Although these screws have a considerably high load
bearing strength, it is not advisable to use them in
high strength applications. The stainless steel, carbon
steel or alloy steel make gives these screws an
additional corrosion resistant property. They are mostly
used in applications where the surface area of operation
is not sufficient enough for the usage of a wrench. This
means that they are often used in machining and assembly
processes which do not exert too much torque on its
body. |

Countersunk head cap screws DIN
7991/ ISO 10642 |
|
 |
| |
Socket countersunk head cap screws Fasteners are
mainly used in applications which require a visually
pleasing fastener with minimal load bearing
capabilities. So, please note that these screws are not
intended to be used in high strength applications.
Sockets whose wear resistance is to be protected in the
long run can use these screws instead of high strength
countersunk screws. It is available in stainless steel,
carbon steel, and alloy steel to bear more wear and tear
while also making it more corrosion resistant.
Dimensional Standards:
IS 6761, DIN 7991, BS 4168, BS 2470, ASME B18.3.5M
Size range:
Metric: M3 to M24

One end of these pins is tapped, and the other is
chamfered for easy insertion. To remove, thread a screw
or tool into the tapped hole, then pull the pin out.
Because they aren't vented, they work best in through
holes. Use them as pivots, hinges, shafts, jigs, and
fixtures to locate or hold parts. Pins are precision
ground for accurate alignment. Breaking strength is
measured as double shear, which is the force required to
break a pin into three pieces.
Pins that meet ASME B18.8.2 specifications conform to
ASME standards for material and dimensions.
Metric pins meet DIN 7979D-m6 specifications.
Steel pins have good strength. |

Our plain taper pins are made to DIN 1B, we also
offer extractable taper pins to DIN 7977 and 7978. As
well as our stocked taper pins, we offer non-standard
diameters up to a maximum of 32mm, non-standard taper
angles, a ground finish and lengths up to 300mm. We
welcome enquiries for split taper pins, which can be
produced to a customers unique specifications.
With DIN standards the nominal diameter is always the
smaller end and the taper is 2% (1 in 50). We can also
supply to other metric standards, inch sizes or
completely non-standard dimensions. We also stock taper
pins in inch sizes to BS46 Part 3.

Socket shoulder screws ISO 7379 |
|
 |
| |
| Shoulder bolts, or shoulder screws, have a long,
unthreaded, cylindrical shoulder that allows for the
rotation of attached parts like pulleys, gears, moving
parts of engines and mechanical assemblies, and rolling
wheels. These screws are also used to attach stripper
plates. The socket head enables high torque fastening
with limited clearance. |

Hex fit bolts Din 609/ Din 610 |
|
 |
| |
DIN 609 Hex Shoulder Bolt (Fit Bolt) with long
threaded portion are in the group Bolts & Cap Screws.
Hex bolts and hex cap screws feature a large fastener
head for distributing clamping load. These fasteners are
used at high tensions and temperatures. Cap screws have
a washer face underneath the head and are used in
precise applications. In Europe, a cap screw refers to a
bolt-type fastener that is fully threaded, whereas a
bolt is the part-threaded equivalent.
DIN 609 Hexagon Fit Bolts with Long Threads is made of
carbon steel, stainless steel A2 and A4. The bolt DIN
609 is installed in the unfolded hole without a gap, so
the neck is pierced by a fine fit and must be ground
after hardening. Such a connection provides not only
accurate positioning of the fastened parts together, but
also the inability to linearly shear. This increases the
service life of the hardware and reduces the risk of
breaking the connection from shearing loads. |

| Standard pull out styles are designed for easy
removal when frequent reassembly is required. They have
a smooth finish and are used in applications featuring a
through-hole. Alloy steel is the strongest of all steel
types. It has high tensile strength and offers excellent
resistance to wear, fatigue and galling. Type Standard
