Features of ss304 Knurled Thumb Screws
Knurled Thumb Screw Title:
Durable M6 M8 M10 Coarse Thread knurled thumb screw and nuts knurled thumb screws stainless cold heading
kurling Head Thumb Screw Introduction:
The core is a stainless steel screw paired with an integrated knotted head thumb screw, which increases manual tightening friction by rolling the head circumferential/top surface. It can be tightened and disassembled without the need for auxiliary tools and belongs to high adaptability quick installation fasteners.
Different from the smooth head design of ordinary hand screws, the twisting screw thumb is more labor-saving and has stronger anti slip properties. The core process identification is the rolling screw thumb, which is the preferred choice for precision assembly and high-frequency operation scenarios.
The core product is SS304 knob led thumb screws (made of 304 stainless steel rolled flower hand screws), which also supports multi specification customization:
304 stainless steel (SS304): a commonly used mainstream material, resistant to atmospheric corrosion, weak acid and alkali, with high cost-effectiveness. It is the basic version of knob thumb screws (rolled flower hand screws), suitable for conventional industrial, precision instruments, office equipment and other scenarios;
316 stainless steel (SS316): marine grade anti-corrosion material, containing molybdenum element, resistant to seawater and chemical media, suitable for outdoor, humid, and corrosive environments for rolling flower hand screw assembly;
Customized version: It can be matched with aluminum alloy, brass and other materials with rolled flower heads according to needs, combined with stainless steel screws, balancing lightweight and durability.
Small specifications: M3, M4, M5, M6, suitable for precision instruments, small panel quick installation;
Medium/large specifications: M8, m10 knob led thumb screw, M12, suitable for heavy-duty scenarios such as industrial cabinets, machine tool covers, and large distribution boxes;
Customized specifications: Supports imperial # 6-32, # 8-32, 1/4-20, etc., suitable for the assembly needs of imported equipment from Europe and America.
Knurled Knob Thumb Screw: Thread length: 6mm-50mm, regular optional, Head size: Diameter: 12mm-35mm, increasing with screw specifications, Knurled Head Thumb Screw Head thickness: 5mm-10mm, supports non-standard customization;
Product Style
The core is divided into knitted head thumb screw (flat rolled head) and knitted knob thumb screw (convex rolled knob head), with the former suitable for flat assembly;
Core production processes: precision embossing/cold heading integrated forming/thread rolling/stainless steel passivation treatment: ss304 knitted thumb screws undergo natural passivation/edge chamfering treatment, etc;
| Thread Size | D(mm) | L(mm) | H(mm) |
| M3 | 10mm | 4/5/6/8/10/12/14/16/20/25/30 | 5mm |
| M4 | 12mm | 5/6/8/10/12/14/16/20/25/30/35/40 | 5mm |
| M5 | 16mm | 6/8/10/12/14/16/20/25/30/35/40/50 | 5mm |
| M6 | 20mm | 8/10/12/16/20/25/30/35/40/45/50/55/60 | 5mm |
| M8 | 25mm | 10/12/14/16/20/25/30/35/40/45/50/60 | 5mm |
| M10 | 30mm | 16/20/25/30/35/40/45/50 | 5mm |
Application:
Precision instruments and laboratory equipment: SS304 knob led thumb screws are rust proof and clean, and the rolling and twisting do not damage the surface of the instrument;
Medical and food equipment: quick assembly parts for medical workstations, food processing machinery, etc;
Molds and fixtures: The positioning and fastening of small molds and fixtures can be quickly adjusted by rolling the screws with a hand, without the need for a wrench, improving processing efficiency.
Knurled Screw Knob Advantages&Features
Knurled thumbs screws significantly increase manual twisting friction through embossed textures, eliminating slipping issues and making twisting more effortless;
The knob head thumb screw and knob knob knob thumb screw are available in both styles, with flat/knob heads adapted to different assembly spaces and operating habits;
Core advantages of 304 stainless steel: SS304 knob led thumb screws have both rust resistance and cost-effectiveness, with a much longer service life than carbon steel knurled screws;
M10 knob led thumb screw and other large-sized models with high structural strength;
