From the manufacturer:
The versatile MiniLock can be used in single holding, double holding or multiples of both single and double holding applications.
• Ideal for hard fixturing as well as for palletizing small parts to be loaded into receivers on machine tables
• The clamp jaw is made from rugged Amco 18 aluminum bronze and the flathead screw is a special alloy steel
• MADE IN USA
Unlike many competitive cam action models, this product employs the same AngLock concept as the world famous Kurt vises. When a quarter turn is applied to the screw, the split clamp jaw is forced both laterally and down, precisely clamping the part and preventing part lift at the same time. In-house tests showed zero lift when the MiniLock was used in several grinding operations.
Features:
• By using stationary blocks or pins, two parts may be clamped by a single MiniLock.
• The versatile MiniLock can be used in single holding, double holding or multiples of both single and double holding applications.
• Ideal for dedicated fixturing as well as for palletizing small parts to be loaded into receivers on machine tables.
• Through the use of a variety of locating blocks, workstops and MiniLocks, several similar parts or a part “family” can be located on a single pallet.
• Clamping jaw made from rugged Ampco 18 aluminum bronze.
• Actuating screw is made from a special alloy steel.
• While one pallet of parts is being machined, the operator can be unloading and loading a second similarly configured pallet away from the machine tool.
• Steps may be machined into the clamp jaw for operations that require parts to be raised above the pallet or machine table.
• The low profile allows for machining of complete top surfaces of parts without having to re-clamp.
• Conveniently uses standard thread sizes and standard hex keys.
• One MiniLock package contains six MiniLocks.
• This item is for the Inch version, a metric version available.
