L H Dottie Co RHP18C Hex Pin Bit 1/8 9/64 Inch 2 Pack

Product Description

The L H DOTTIE CO RHP18C is a two-pack of hex pin screwdriver bits sized at 1/8 inch and 9/64 inch. Hex pin bits, also called pin-in-hex or security hex bits, are designed to drive tamper-resistant fasteners that feature a center pin in the hex socket. These bits are a standard hand-tool accessory used by electricians, HVAC technicians, plumbers, and general trade contractors when working with security fasteners found on equipment panels, enclosures, and access covers. The two-piece pack covers two of the most common hex pin sizes encountered in the field.

Hex pin bits are commonly used in residential and commercial service work where tamper-resistant fasteners are specified by equipment manufacturers. Typical applications include electrical panel trim screws, HVAC equipment access panels, and other assemblies secured with security hex fasteners. Having both the 1/8 inch and 9/64 inch sizes in a single pack makes this a practical addition to a field technician's bit set.

Key Features

• Two-pack includes both 1/8 inch and 9/64 inch hex pin sizes
• Designed for tamper-resistant pin-in-hex fasteners
• Compatible with standard screwdriver bit holders and power drivers
• Covers two of the most frequently encountered hex pin driver sizes in trade work

Compatibility

Designed as a standard replacement or supplemental hex pin bit set suitable for use with common 1/4 inch bit holders and compatible screwdrivers or power drivers accepting standard bit shanks.

Installation Notes

Hex pin bits are installed and removed by hand tool or power driver — ensure the bit is fully seated in the fastener before applying torque to avoid stripping the socket. Confirm the correct size before driving to prevent damage to security fastener heads. No power shutoff is required for bit changes, but always de-energize equipment before servicing any fasteners on live electrical or HVAC assemblies per applicable NEC and local codes.
