Product Description

The one letter countersunk head bolt stands as a vital, multifaceted mechanical fastener, renowned across numerous fields for its distinctive design and robust functionality. Below is an in-depth exploration of its features from various perspectives:

• Structural Features

Head: Designed with a flat top surface and conical sides, the head effortlessly sinks into pre-processed countersunk holes upon contact with the connected part's surface. This ensures a smooth, uninterrupted flatness, free from obstructions that might impede additional installations or detract from visual appeal. A strategically placed straight groove enhances efficiency, allowing for seamless tightening and removal with a straight screwdriver.

Screw: The screw portion, adorned with external threads, pairs harmoniously with nuts or internally threaded holes to forge a steadfast connection. A variety of screw length specifications cater to diverse usage scenarios, perfectly accommodating the thickness of various connected parts.

Material: Countersunk head bolts can be crafted from a range of materials including carbon steel, stainless steel, and alloy steel. Carbon steel boasts cost-effectiveness and strength, albeit with moderate corrosion resistance. Stainless steel excels in resisting corrosion, ideal for damp, corrosive environments. Meanwhile, alloy steel is engineered to deliver exceptional strength and toughness through alloying elements.

Working Principle: Usage begins with machining a suitable countersunk hole within the connected part. A straight countersunk bolt is then threaded through this hole and other components. Securing a nut onto one end initiates axial tension, facilitated by rotating the bolt head's groove with a straight screwdriver. The resulting interaction between threads generates friction and pre-tightening force, ensuring a reliable connection.

• Specification Standard: Adhering to national standards, specifications are denoted as "thread specification (nominal diameter) x screw length". For instance, M4 x 20 signifies a 4mm nominal diameter and a 20mm screw length. Common thread specifications range from M2 to M6, with screw lengths spanning a few to hundreds of millimeters.

• Application Scenarios

Furniture Manufacturing: In the realm of furniture production, maintaining surface appearance and flatness is paramount. Straight countersunk bolts become indispensable for connecting boards, such as in tabletops, table legs, and cabinet components.

Electronic Products: The meticulous design of electronic devices demands flat surfaces and compact internal spaces. The straight countersunk head bolt ensures seamless integration, preventing protrusions that might hinder assembly, thus securing shells and internal components in mobile phones, computers, tablets, and beyond.

Decoration and Renovation: Within interior decoration and renovation, these bolts secure decorative panels, door, and window accessories, preserving surface elegance while enhancing aesthetic appeal.

Mechanical Equipment: For components necessitating surface flatness and low-stress connectivity, straight countersunk bolts serve as ideal connectors, evident in equipment protective covers, small brackets, and more.
