How's it going? This is Yamazato from Hanshin Neji (Thailand)! This time, let me talk about a thick bolt (Large Diameter Bolt). Our Company is responding to all kinds of consultations and providing prompt delivery related to thick Screws, such as cap bolts with Large Diameter hex holes, high-strength hex bolts, attached washers and hex nuts. Please leave any custom-made items for us. We will never reply, "We cannot!"

Even in Thailand, we deliver High-Quality Large Diameter Bolts within 3 days at the minimum!

Among the many bolts, bolts having a diameter of 36 mm (M36) to 64 mm (M64) are particularly called as Large Dia. Bolts. It’s thick, hard, and heavy. It is a huge screw like an iron array. In Thailand, it is used mainly to fix molds for presses and forging in the automotive industry. Such heavy-loading Large Dia. Bolts require strength and durability. We must strictly prevent the screws from loosening or breaking in the production process. Our Large Dia. Bolts are Japanese-made with excellent quality. We will deliver screws that can use feeling assured from Japan to Customers in Thailand in three days at a minimum.

Hot forging and rolling, maintain a material grain pattern. This realizes High Strength and Long-life large diameter bolts.

Large Diameter Bolts are also produced and distributed in local Thai markets, but the manufacturing method is different from the Japanese-made bolts we handle.

While our Japanese-made bolts are from Hot Forging, most of the local things traded are made of Lathe Manufacturing. Although cutting is an excellent processing method in itself, the fiber-like tissue that makes up the metal fiber flow (grain flow line) is destroyed. So, it leaves uneasiness in the neck of the screw, the screw part, the transition part between the screw and the body. It takes time to fabricate, and the edge loss and steel turnings come out, too.

In addition, the screw increases the strength further by the heat treatment applied after forging. By quenching and tempering at a high temperature of around 800 ℃, the finished product can obtain higher strength. The world's best heat treatment technology! The Large Dia. Bolts we deliver are produced with these high technologies that are unrivaled.

Screw delivery service Screw REO 250 by air flight was born!

The short delivery time is our greatest strength. Our head office in Japan stocks and sells bolts up to M64 as general standard products, so we send them directly from the warehouse to Thailand.
