This C clamp, 100 x 60 mm, is a general-purpose G‑style clamping tool designed to hold workpieces securely during gluing, drilling, soldering, welding and light fabrication. The two dimensions indicate maximum jaw opening (100 mm) and throat depth (60 mm), making it suitable for small to medium workshop tasks where a reliable, manually‑operated clamp is required.

The frame is manufactured from robust cast iron with a protective enamel finish to resist chips and surface corrosion. The clamp screw is machined from heat‑treated steel to a strength grade equivalent to Class 8.8 and is zinc plated to improve corrosion resistance and sliding action. The screw uses an ISO metric coarse thread form, manufactured in accordance with ISO metric thread standards (ISO 68‑1/ISO 261), and runs smoothly on a forged T‑bar handle that provides positive manual drive. A hardened, swivelling pressure pad on the screw ensures even distribution of clamping force on irregular surfaces and protects the workpiece from marring.

This style of C clamp is widely used across woodworking, metalworking, automotive repair, general maintenance, and hobbyist applications. It is particularly useful for holding small assemblies during adhesive cures, tack welding, trimming and layout work where precise temporary clamping is needed but portability and quick adjustment are important. Tradespeople and workshop users value C clamps for fixtures, jigs and as auxiliary clamp points where bench vices are not available.

Key benefits include the durable cast iron body for consistent clamping geometry, a heat‑treated screw for high tensile strength and wear resistance, and corrosion protection from the enamel body finish and zinc plated screw. The ISO‑conforming thread form ensures compatibility with standard replacement screws and accessories, while the swivel pad improves contact with uneven surfaces.
