Master Series Hardware Nail & Screw Silicone Urethral Sounds

How the Nail and Screw Feel in Use

These two silicone sounds are smooth, slightly yielding rods that bend with your body instead of fighting it. Each one is shaped like a piece of heavy duty hardware. The nail glides in with a clean, even surface and a hexagonal profile. The screw follows a spiral texture along its length, so every slow inch of insertion and withdrawal brings a rolling, ridged sensation. Pick the sleek feel or the threaded one, depending on the mood.

Hardware-Inspired Design Details

The industrial theme comes from the shapes themselves. Both sounds are finished in black, which suits the shop-floor look and keeps the pair understated in a toy drawer. The set includes:

• One smooth hexagonal nail, 6 inches long and 0.3 inch in diameter
• One spiral-textured screw, 6 inches long and 0.25 inch in diameter
• Black silicone construction on both pieces
• Latex-free and phthalate-free material

The slimmer screw and the slightly wider nail give you two distinct sizes to work between, and the matching 6 inch lengths make switching from one to the other feel natural.

Build & Quality

XR Brands makes both sounds from premium silicone with a silky surface. The material is flexible enough to follow your inner curves, yet each rod keeps its shape so the hex edges and spiral ridges stay crisp. The set weighs 0.15 lb, so neither piece feels heavy or awkward in the hand during slow, controlled play. For anyone building a kink collection around fetish themes, this duo adds a playful, hardcore edge without extra parts to manage.

Lube and Care

Do not pair these sounds with silicone-based lube, since silicone on silicone can break down the surface. Reach for a water-based lubricant instead and apply it generously for a smooth glide. Cleanup is simple: wash both pieces with mild soap and warm water, rinse well, and let them dry fully before storing them together.
