Dairy Blind Nut
What is a Dairy Blind Nut

Allen Cap Screws, also known as socket head cap screws, are high-strength fasteners designed with a cylindrical head and internal hex drive. These screws are tightened using an Allen (hex) key, allowing for a secure and flush fit even in tight or recessed spaces. Their clean, compact design makes them ideal for machinery, automotive, electronics, and structural applications requiring precision and aesthetics.
Allen Cap Screws are widely used in high-torque and high-performance environments due to their superior clamping force and space-efficient profile.
