Double Shear
Product Code : LSK-MTE-10500
Double Shear (SKU LSK-MTE-10500) is a shear test attachment that determines the shear strength of cylindrical specimens by shearing them across two sections at once. It fits the area below the loading platform of the Universal Testing Machine and is used in strength-of-materials practicals at engineering colleges and polytechnics. Science Lab Supplies produces the attachment at its manufacturing unit, Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and supplies colleges, contractors and distributors without intermediaries.
Specifications
A specimen holder fits the lower ball joint of the testing machine and a shear strap holder fits the upper ball joint. The copper specimen passes through the holder and the shear strap, a dowel joins the two sections, and the machine's pump raises the ram force until the specimen shears.

Applications and Experiments for the Double Shear Attachment
The attachment finds the shear strength of a rod by loading it in double shear, so the specimen is cut at two cross-sections. Because bending is eliminated, the result is cleaner than a single shear test, where the specimen can bend before it shears and must be corrected for.
- B.E./B.Tech civil and mechanical: shear strength of a metal rod in strength of materials.
- Diploma engineering: comparing shear and tensile strength of the same material.
- Design of pins, rivets and dowels loaded in double shear.
Standard Scope of Supply
The Double Shear attachment consists of the specimen holder, the shear strap holder, the shear strap and the connecting dowel, used with copper specimens. Not included: the Universal Testing Machine, which provides the load. Spare specimens can be requested on the quotation.
Packing, MOQ and Lead Time
One attachment or a batch for several testing machines can be priced. The quotation states packing, delivery time and price for that quantity, and the Universal Testing Machine or other engineering lab equipment in India from this range can be added.

Frequently Asked Questions
Why test in double shear rather than single shear?
In a single shear test the specimen can bend before it shears, and this has to be allowed for. In double shear the specimen is cut at two locations, bending is eliminated and the test is much simpler.
Which machine does it fit?
It fits the area below the loading platform of the Universal Testing Machine, with the specimen holder on the lower ball joint and the shear strap holder on the upper ball joint.
Who manufactures the Double Shear attachment?
Science Lab Supplies does, in its own workshop at Saha, Ambala, India. Buyers deal with the manufacturer directly for quotations and technical questions.
What materials can be tested?
The method is valid for materials with a maximum tensile strength of 1300 N/mm². The described procedure uses a copper specimen; ask via the contact page about other specimen materials.
