Sealey TRX-Star Socket & Security Socket Bit Set - 38 Piece

The TRX-Star and Security TRX-Star bits are made from durable S2 steel.

The 'H' indicates that these are 'Security' or 'Tamper-Resistant' Torx bits, featuring a small pin in the center to match the corresponding hole in security Torx fasteners.

Standard TRX-Star bits (e.g., T20, T25) can be used with standard Torx screws. Security TRX-Star bits (e.g., T7H, T8H) are specifically designed for tamper-resistant fasteners with a center pin and may not fit or function correctly in standard Torx screws.

The knurled ring is designed to provide a better grip on the socket, making it easier to handle, especially when your hands are oily or greasy.

TRX-Star sockets (Female), often referred to as E-Torx sockets, are used for external Torx fasteners, which have a bolt head shaped like an external star.

Clean the bits and sockets with a dry cloth after use and store them in the provided case in a dry location to prevent rust and corrosion. Inspect for wear periodically.

The set includes bits and sockets for 1/4", 3/8", and 1/2" Square Drive tools.

Ensure you are using the correct size TRX-Star bit for the fastener. Apply firm, consistent pressure directly into the fastener head while turning. Check the fastener for damage or debris in the recess.

Verify that you are using the correct drive size (1/4", 3/8", or 1/2") for your tool. Ensure the fastener head and the bit/socket are free from obstructions or dirt.

Cease use immediately. You may be applying excessive force or using the incorrect tool for the application. Inspect the bit and fastener for damage and consider using a higher torque tool if appropriate, or a specialized extraction tool if the fastener is damaged.
