Sealey Hex Key Set - 30 Piece - Long/Short Arm - Metric/Imperial

The hex keys are constructed from durable Chrome Vanadium steel, known for its strength and resistance to wear.

Yes, the set includes both metric sizes ranging from 0.7mm to 10mm and imperial sizes ranging from 0.028" to 3/8".

Long-arm keys provide greater reach for accessing recessed fasteners and offer more leverage. Short-arm keys are more compact and suitable for tighter spaces or when less torque is required.

This is a 30-piece set, featuring 15 long-arm Imperial keys and 15 short-arm Metric keys.

The product comes with a lifetime guarantee, indicating Sealey's confidence in its durability and quality.

The set weighs approximately 0.94kg (nett weight: 0.78kg).

The set includes a folding storage case for organization and portability. While functional, it is designed for practical storage rather than heavy-duty professional workshop organization.

Double-check if you are using a metric key for a metric fastener and an imperial key for an imperial fastener. Ensure you are selecting the correct size from the set; sometimes closely sized metric and imperial keys can be confused.

Ensure you are using the correct size hex key that fits snugly. Apply steady, even pressure. If the fastener head is already damaged, try a slightly larger size key or a specialized screw extractor tool.

This can occur if the keys are stored in a damp environment. Wipe the keys thoroughly with a dry cloth. For light rust, a fine-grit abrasive pad or steel wool can be used, followed by a light oil coating for protection. Ensure the storage case is kept in a dry place.

Ensure all keys are correctly seated in their slots. Consider using a permanent marker to label the slots if the molded markings are unclear.
