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 suits strength-of-materials practicals at engineering colleges and polytechnics. Science Lab Supplies manufactures the holders, strap and dowel in Saha, Ambala, India, at Plot 448, HSIIDC Industrial Area, and the factory deals directly with colleges, contractors and distributors.
Specifications
Every part and limit of the double shear attachment is set out in the table. In short, a specimen holder on the lower ball joint and a shear strap holder on the upper ball joint grip a copper specimen, 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, with the rod diameter measured on a Digital Micrometer to find the sheared area.
- Diploma engineering: comparing shear and tensile strength of the same material.
- Design of pins, rivets and dowels loaded in double shear, with copper rod cut to length using a Hacksaw Frame.
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. The Universal Testing Machine that provides the load is a separate item, and it can be quoted together with spare specimens on the same 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?
The holders, strap and dowel are made by Science Lab Supplies at its own Saha, Ambala site, so technical questions and quotations are answered by the people who make the attachment.
What materials can be tested?
The method is valid for materials with a maximum tensile strength of 1300 N/mm². The test procedure uses a copper specimen; ask via the contact page about other specimen materials.
Related Testing Machine Parts and Shear Apparatus
The Universal Testing Machine accepts several optional test parts besides this attachment, and the other machines here extend shear and strength testing to torsion, bench tensile work and soils, so a laboratory can plan its practicals around one loading frame and quote them together.
- Universal Testing Machine — four-column steel frame whose hydraulic ram pushes up the loading platform.
- Brinell Indenter — hardened steel ball and scaled magnifier, fitted above the platform.
- Coil Spring — held between two metal bosses while the machine compresses it.
- Beam And Leaf Spring — leaf spring on its rollers over two flat supports, with spanner and hexagon tools.
- Bench Top Tensile Testing Machine — aluminium bed stiffened by tie bars, with about 400 mm of lead-screw travel.
- Torsion Testing Machine — 60:1 worm-drive strain head on a platform that locks anywhere along the frame.
- Direct Shear Apparatus — shear box for soil specimens of 60 or 100 mm diameter, or 60 x 60 and 100 x 100 mm square.
